Guys what will happen if you accidentally lost the copy of your private key?..it's still possible to transfer your tokens to your other wallet using your wallet address..?? Does anyone know?..thanks in advance

No one will be able to access your wallet if you lose PK, and no one can help you to access your wallet again if your PK is lost

I think you same like loss of your money there in wallet and lost access to wallet.
So private key is like our money. Keep it well.

I assume that you are using an Ethereum wallet and not a Bitcoin wallet cause you are pertaining to tokens.

Private keys is the most essential with any kind of cryptocurrency wallets so if you lose it then there is no way you can retreive your wallets. You have no any insurance in getting back your tokens anymore but if you still have an access to your Keystore File(UTC/JSON) with password then you can still login to your Ethereum address.

no you can't transfer your coins if you lost your private key. it is the most important thing in accessing your wallet without that your coins will be forever lock, in that situation you can ask mod/dev of a certain coin if they can help you get back all your coins from lost private key.

Usually it's impossible to recover your cryptocurrency funds if you lose the private key to your cryptocurrency address.
However, if you use HD wallet and still remember mnemonic words, you could restore your lost funds :)

Also, if you still have wallet file and forgot mnemonic words and private keys, but remember parts of the password. There are services which could help you restore the wallet.

you cant do that if you dont have your private key you cant open your wallet because that will be your password. sorry to say that your token will be their for how many years.

A big NO...

Private key is tied up with bitcoin address and it is key to use any bitcoin held on that bitcoin address, without this key nobody can move those bitcoin out of the address.

If you have made that bitcoin wallet from blockchain.info like web wallets than you might have secret seed phrase to restore your wallet.

So better to keep it in a safe place because if you loose it, you probably loose your money. Always have your multiple back up data about your PK so if one wast lost you till have other option. PK is the most important thing in your wallet, use it well.

Yes, but you will need a backup for that purpose. A private key is not a password and hence you can not reset it using any link/email id/2FA and etc options, you must keep the backup for it in order to use it in case of emergency.

There are the people who lost their private keys / wallet.dat file and hence lost the entire control from their wallet. Understand that after losing the private keys, your bitcoins are still on the network but since no one (including you) knows the private keys to spend those funds, those Bitcoins are useless and hence lost forever.

Sorry to break the sad news dude, but it lost your Private Keys, say bye bye to your coins or tokens. How about your JSON file though, I'm assuming you are talking about MEW here because you have mentioned tokesns? did you back it up or not? Their may be a a slim chance to recover it if you made a proper backup. But other than that, you won't be able to recover them. You know the drill, if you just followed it, this will hot happened to you. Sorry for you lost.

Private key is the most essential thing to access a wallet and once lost is almost impossible to recover unless backups were made and/or the wallet service provided recovery phrases which were backed up. In any case, offline backups of each would ensure total safety of the wallet since you would be in control of the coins without anyone else's access to it.

Unless you have your coins on a platform like Coinbase ( they dont give you your private key ) then you are pretty screwed. Which is why security is very important regardless of how much you are investing.

your coins will lost forever too if you lost your private key. if you create a wallet you should always make a back up of all the information created for a certain wallet

i am really sorry for you man :/ how many btc ? probably are away ...

It depends on the type of wallet you use. Some wallets store your private key with them so you just need login id pass to enter the wallet and make transactions but if you are on a standalone private key wallet then you have surely lost your funds forever there is no way one can gain access to a wallet without private key nor do we have such technology which could do a brute force attack to guess up the private key.

No, it is the only one way to deal with the Bitcoin. It is needed for security, so you should keep your parsonal data more carefully. Some people use backups for these needs (even backups on pieces of paper).

as far as i have know, you cannot retrieve you wallet anymore if you lost your private key and you cannot transfer your token into your new wallet if you cannot  open the old one. private key is very important to access our wallet.

If your private key goes in wrong hands then he may empty your wallet. And without pvt key no one can access your wallet not even you and you also cannot make transfer into new wallet.

you can do nothing, even a recovery process never can get it i dont know so please be carefull with your private key

If you lose your private key you will no longer use it to transfer and to deposit. Tour private key is just simply your password so that no one can use your wallet. So you must be careful with your private because in just simply posting it your coins will disappear

Your private key serves as your password, pin code, and your only sole access to your wallet. If you lost it, then you can never access it. Even if you know your address, you can't use it to access your wallet, only that, you can view your balance. Private key needs to be in your safe place or always have a back up for it. You must always secure your private key.

you never could access your wallet anymore if you lost privat key.. You should make lots of copies privat key and keep it in a safe place.. nobody can help you to recover your wallet, of course you have to make a new wallet..

If you still have the wallet on your pc, you can just dump it again.

There are also tools that generate private keys online, based on your adress and wallet.dat file, but I can't confirm these actually work.

Let's hope you'll take this as a lesson, and that the wallet didnt contain to much coins.

Good luck.

Which wallet are you talking about? If you are asking bout a private key for myetherwallet then your money is gone without the private key.

it's a big deal, if you lose your private key, it's the same as you lost it all ..
your coins and wallets will never be open again.
and you have to create a new wallet, then collect the coins again, so you have to keep your private key very carefully

You totaly lost all of you money.Because any one can get your money by this privet key.it's harmfull for you digital currency.you should transfar your money on your another wallet as soon as posible.thank you.

Private keys should be kept properly and should not be disclosed to anyone. If you lost it you can't access your wallet anymore and your coins will be stagnant and locked in there. That would be the worst thing that can happen to anyone.

No, unfortunately you are unable to access your wallet if you dont have your private keys. That would mean your money is lost. So you must always guard your keys with your life. Always keep them in a safe place. In more than one safe place preferably so that if the house burns down, you will still be able to access your keys.

what kind of wallet you have?
i use HD wallet blockchain.info and use it without need to know my private key.only need password and 12 words

I am really sorry to say it' impossible you can't transaction any amount without privet key from cryptocurrency, the private key is just not a private key it's money, more information for you private key don't share any other person though he very close to you. it's my suggestion you can save your private key Google Drive or in an External hard disk.

If you do not have access to a private key, you can not manage money. It's good. Because that's why we love crypto assets, that only the owner has the right to decide what to do with them.

basically if you lost your private key, you will never retrieve it again unless you will try to contact their support for taking chances.
certainly there is no way to go backwards from the public key to the private key, that would mean that anyone could steal your Bitcoin

Many wallets don´t use private keys. They manege public addresses for you to send or receive cryptos. Try to use those ones, next time.
As everyone said, the private key is like your life in the blockchain, and you can recover it

Private keys are important files with any type of cryptocurrency wallets. So if you lose it, you can not use your wallets. Because it will be your password

With you lost key those bitcoins will be lost. If you still have access to that wallet send everything to a new wallet. It is important to make multiple copies of your keys for this reason.

You cannot recover your wallet without private key. AFAIK the key itself can't be recovered as it is based on strong cryptography algorithm

You cannot get back your funds if you lost your private key. It is very important in crypto. You are unlocking your funds on the blockchain with your p-key. If you lost it then you don't gain access to it.

if you lose your private key, you will not be able to access your wallet again, you have to create a new wallet, of course also lose the contents of wallet that lost its private key ..
that's why you should keep your private key very carefully

If you only lost your copy but you're still able to manage your Bitcoin, then it's not really a problem. Because you still have the ability to make either a transaction to a different wallet of yours or export the private key again. But if you're copy is lost and it is not included in the wallet then your funds are gone forever. So make sure you don't lose them.

Private key is very important without it we cant make access in our etherwallets. If we lost it everything and all the tokens that weve earned will be worthless. So we must keep it safe. As an alternative we can also make another copy of it just in case we lost the other one.

if you loss your private key that means your account gone.you can not get back the account again.so make it more secure and always store it multiple places.

If you lost your private key then, that will be your wallet's end. Because that is your password on your wallet or the key to your safebox. So it means you need to create back ups of it.

You cannot retrieve it anymore unless you have saved it from your desktop or any device, there should be a file that will be automatically download after you create your wallet, you can access it again by using that but if you didn't have that then there is no way you can retrieve the tokens that is currently on your wallet. Find the wallet file in the device you used when you create the wallet, just be sure you neither delete it or it got lost.

If you are stuck in such a situation sadly there is no way out. Losing private key means losing access to the pathway of your wallet. No one can help you transfer funds from this wallet. Only case where in such a thing is possible is if you are already inside your wallet.

Yes cracking a private key is certainly impossible as its a very long alphanumeric code. If even with the best technology available today we try to make a brute force attack to find such a key it would take years to find out your combination.

if u lost your private key then forget your money in it
...

it is a serious problem, because if it happens you lose your wallet .. and you will never be able to access it again.
therefore we must keep our private key very securely, do not let others know, and never publish it

if you lose your personal wallet key, you can not open it again, and will not be able to transfer its contents to another wallet, because you have lost access to your wallet
if that happens, you just have to give up, and someday you have to keep your private key well, so that the same incident will not happen again, because it will hurt your own

If the private key is myetherwallet if you lose it you can not open your wallet. You can not transfer your tokens/money. As a result you will lose your tokens/money forever. So you should keep your private key carefully.

Say good bye, but if you have a back of your wallet. Just try to use if you can retrieve you wallet. Good luck.

Well,  I think everyone knows what will happens if you lost the private key,  you couldn't open your wallet.  So, the thing is be conscientious with your privacy. There ia no other way to open your wallet.

this is a tragic, one fatal mistake for you. no one can access your wallet if the private key is lost. I thought you were careless

There is nothing you can do about that, sorry for your loss. Maybe try RECUVA software :)  it worked for my pictures

We have the same situation here, I don't totally lost my private keys but I cannot access my myethereum wallet using the private keys I think there is a lacking or excess code in my private keys.  I also don't know what to do or how to retrieve it. I guess we can't do anything about it anymore. My tokens are lost forever.

If you lose the private key, you will not be able to trade with the coin in your current account. Because the private key is very important, it decides about the property you have in your wallet. When creating a wallet, I see the notice that if you lose the private key, there is no way to recover the wallet as well as the money in it. You will lose all your money and no more access to your wallet anymore. So this is also a lesson for you to be careful next time to save the private key.  ;D

That would be the saddest thing to happen to someone who have cryptocurrency. Losing your private key means permanently losing your coins. No one can access your wallet if you don't have the private key. It is not possible to transfer your tokens using only your wallet address, you really need the private key.

Nobody and nothing will not help you if you lose the key. You need to make a copy of the key and store it in a safe place and then everything will be fine.

No one can help you with your private.
But as long as you can open your wallet address and you know the password of your wallet then you can retrieve your private key.
Keep it safe.
Never let it fall into anyone's hand.

if anyone dont get your private key, and u lost like you forget your key or somehow deleted then nobody access yor wallet .

So mean you permanently lost your COINS, unless you keep the private key in the computer, can find file recovery experts help you restore private key to this problem, if the recovery fails, means lost permanently.

Losing the private  key will result in losing the money in your account. Your private key is more important than the balance in crypto world. Keep it safe. Keep 3-4 copy text for the priv keys.

in my opinion, can not access the wallet if you lose the keyword, because the keyword is the most important thing to open your wallet so you can open what you have

I think that if you lose a private key, you will be able to restore access to the wallet only if you previously downloaded and saved the file, which always offers to download any wallet during registration

If you don't downloaded and save the file, unfortunately you lose all your funds. Take care next time.

I believe this is an ethereum wallet because you mentioned about token. You can still retrieve you token if you save your JSON file and you still remember the password that you use. Once you access your wallet using JSON file, create a new wallet and make sure to have a backup of your private key and JSON file in case of accidental lost of your private key.

nothing you can do if you lose a private key, there is no guarantee of aps wallet if you lose private key. This means we can not:
1. Recover your private key
2. Access you account
3. Recover or reset your password
4. Reverse or cancel transactions
5. Recover your account
6. Send your Tokens from one address to another

Yes it is a big mistake. Private key is the gateway to the account we have, lost the password and private key will only make us frustrated.
That's why it's important to keep a private key, because with a private key we can access the account we have whenever we want.

No one can access your wallet if you lose your private Key, and nothing can help you access your wallet again if Your private key is lost. Just god knows. ;D ;D ;D

That's one of the very first warning one gets when creating a new wallet that one should keep his/her pk safe if lost it can't be recover so I doubt if you will have access to the such wallet

A private key is very important and you need to have personal copies of it when you lose it. Even cracking private keys is an impossible feat.

Aw that's one of the worst things that can happen to you too bad.

I hope it will never happen to me, because the private key in my opinion is very important in accessing our wallets and without it we will not be able to transfer coin.need accuracy so that our private key is not known to others let alone lost.

you are SOL..no hope :(

No one can help you if you lost ur Pk
Better get its copy in  any note of yours

This is the sad the part losing your private key because losing it will not recover your tokens. The important in ethereum wallet is the private key this is the way you can open, transfer and deposit token in your wallet. Without it no other ways to recover.

Im sorry OP but you cannot retrieve it anymore the moment private key was lost, the last option you can do is to retrieve the json file in your hard drive if you cannot do it then it is totally lost.    

you will not get your coins anymore because to sell the coins you need a private key. so I'm sorry if that happens, because the results of your hard work will just disappear.

Hi! Sorry to hear about that. But i would like to assume you are using etherium wallet probably, if that so, before signing up you see that there are notes and disclaimers provided. That is why keeping your Private Key secure is the first priority to make. Transferring to other wallet and to be able to do so means you still need to access the account where your tokens are, but since you lose the private key i think it is not possible to open it of course and more to transfer the balances.

If the private key is lost, it means that you have lost the bitcoin assets forever, which many people have lost in the past. ;D ;D ;D

Thats sound bad

It is right. Private keys are too important, and losing it will really  cause you a big trouble.
 Unlike other accounts or wallet, some  wallet used passwords instead of private keys and it is recoverable once you forget it but passwords has a possibility to cracked or hacked by hackers thats why it is still risky. But using private keys, even you cannot recover it once you lose it. It is really secured. It only depends on you if you take care of your private keys you wont lose it. Just like mine, i save my private keys in my phone's secret vault and also by having its backup in my google drive. Cool.

No, you can't transfer your coin just with an address, because if it's possible then we can steal other people's coins just by knowing their address.
As far as i know, there's nothing you could do if you lose your private key, since it's the way to open and access your wallet.
What you need to do is just let it go, and make other new wallet. Don't forget to back it up many times in many places though, just in case the same thing happens again.

if you lost your private key, its the end of your bitcoin assets. In etherium wallet, once you loss it, you will loss your access to your tokens and I think it is really impossible without it.

Damn that must indeed really suck, since bitcoins is really expensive, wouldn't it be prudent to store your private keys in a very secure location where you wouldn't easily loss all the money that you have stored in your wallet.

Thats the bad thing that you gonna regret if you lost the copy of your private key. You can not access and one can access now in your wallet. And all your tokens are in absolute black cold place that no one could ever get.

Nope, there's no other way you could retrieve your wallet once you lost your private key. Even the platform itself couldn't help you with that. Try to be careful next time. Because your private key is really your only security against those hackers/scammers so please be extra cautious next time. There are a lot of ways you could back it up. But the damage has been done, and I'm so sorry that your portfolio is gone.

if the personal key of the wallet is lost then you will lose the entire coin in it. losing a personal key to a wallet is a very fatal mistake, for me it's a huge loss if in it is a very valuable coin.

If you do not know your private key then you can not do the tokens transaction: You understand that the wallet is inserted: Then you have to make a new wallet.

losing private is worst part of Bitcoin nobody can recover Private keys only way is to protect it write it on in any dairy or else store in pen drive

Privet keys is the main things of saving your money safely.In this crypto world a lots of people lost there money by lossing there privet keys.Because your privet keys belongs all of your docoments and transection of your account.You should write your privet keys in a note to safe and also keys don't share with anyothers,thank you.

No private key -> no funds.
 
It is simple as that, if you are using a wallet that requires to you paste the private key in there everytime that you want to send funds, then you are fucked.

If you are using a hardware wallet, then there is no problem, but better to buy a new one and move the funds.

There's a lot of problems in wallet so yours is the worst because you lose private keys,me everytime i earn tokens i will exchange that fast because the price of it can become low or high so for the sure thing that is my strategy then convert to btc after that invest in some trading site,I think also this question is already see in the first page of their site because this is the most need to save and to safe.

Private key is what you should not lose. All you money is keep on the private key. If you lose PK - you lose your money.

Unfortunately it is true. You can lose your passport but not private key. Because you can apply for a new passport by saying it is lost but if you lose your private key there is nothing that you can do.

If you lose it then it is just like you lose your money in that wallet, it is very hard to know the private key of one account and it is impossible to have if you do not have the exact copy of it. Sorry for your lost.

your fund will lost forever if you loose your private key, your private key or json file is the only way you can interact with an address of ethereum to control the fund inside the address

In decentralized wallets private key is the only source to access your wallet. You should always keep a double backup(both in physical and digital form) of your private key. There is no alternative to access the wallet without private key or seed, so nobody can really help you in this matter.

Hi. Unfortunately no you cannot. If you lost your private key or PC or all this things it's mean you lost all! But you need keep control and just relax! Maybe you will find the copy or this situation can be changed somehow.

You can't do it using the wallet address. However, if you have any one of these (Keystore / JSON File / Mnemonic Phrase) then you can access the wallet and send the tokens.

If you lose your private key then everything is lost, it is that simple, there is no way to get it back, now if you have the seed words of your wallet you could recreate your wallet and create the private keys once again, so make an effort to have that information as well in two separate places that way it will be almost impossible to lose your coins.

private key is the main access so you can get into your wallet balance, if you have lost the private key you will not be able to draw balance in your wallet, be careful with it

yes i agree with your opinion, if lost private key, you can still access to your wallet by using keystore file, if the lost private key is for ethereum wallet

Yes.I agree.You should always have a list of your private keys then save it in a memory card maybe.Your wallet contains of your most valuable amount so make sure to be cautious always.Or do not put big amounts in your wallet because in times like this,you will really have a hard time recovering once you lost your android phone together with your private key.

losing of your privatekeys also losing of your saving always take care of all your privatekey or your password
put into safe keep it with duplicate copy into another storage to avoid losing of your saving.

losing of your private you ca't open your wallet for a lifetime you need make another one amd make sure keep your keys
into safety stoage.

Right but I think upon reading he did not back up it too that's why there are no reason for him to retrieve his wallet and the best thing to is to start over again with the newly created wallet so you can now start and forget what happen to your previous eth wallet.

you should be more careful with the private key, because once lost or forgot will be very difficult to be able to access the balance of your wallet and do your wallet transactions

Cryptos give you freedom, but it comes with 100% responsability for you - if you lose your private keys you lose your money and nobody is gonna save you. Responsability is only yours.

I am sorry dis will be the end of that wallet. Your private is expected to be kept on a soft copy and a hard copy. It is likely to be the reason why some people have to write this keys as a password. Cryptocurrency is likely to be the next phase of payment globally. Cryptocurrency is gone beyond just a currency, its an asset and can be delivered to another generation coming.

If you lost your private key then you cannot do transfer your tokens to other wallets, recover or reset your password, and recover and access your wallet account. Your private key is the most important thing in order to access your wallet.

Of what happen to you now, is just a source of learning for all specially those people that are new in crypto and really no one can recover from such loss. To avoid from losing all the money you have stored in your wallet it is necessarily that you have a back-up copy in all accounts. To have a safe keep of it, you can put it on the banks considering that is an important documents of your life.

that means you've lost your access in bitcoin, but if you have a backup so just change your private key for sure, to prevent from hacking your account.

Usually lost of private key is lost of your wallet. You can't restore your wallet using wallet address only. However, you can try to write in wallet support. If you had wallet verification you can try to restore it.

You will loss all your money,private key is the password for your wallet adress.So keep it save well

That is very big problem if you lost your private key you cannot access your wallet,there is no other way to recover your private key,if you lost your private key you lost also your money and same as you lost your properties,that's why this is big lesson to all newbie's here in the furom that save your private key and keep it safe always or save it in your harddisk so that you can restore it and you will consider your private key as your private documents because if you lost it you will lost also your profit.

I will try to address your question in maybe a little bit more optimistic way than all the others before me. First, from what you ask and from your doubts I infer that your knowledge of the bitcoin and related matters is very limited. And it gives me hope to help you.

So you are saying that you lost a copy of the private key. I am thinking, that maybe following some advice you created a backup copy of the private key and then you lost it. BUT, maybe the original private key is still where it was, i.e. in some file created by the software for your wallet. So I suggest you simply try to set up a new wallet and try to move your funds from your original wallet to a new wallet. If I am not mistaken, you may as well succeed.

Good luck! Let me know what happened. You may tip me :) with BTC: 3NK7xMkrNYCFBj6rRB3wvusugatvwVxCSC

If you lost your private key, then let me tell you that you are fucked, if you were just using a browser wallet, maybe you can join in there with your password + 2fa authenticator.

Otherwise, you are really fucked man, there is nothing that you can do.

u lost private key  of any wallet of ether u can lost all sotre  and save of ethers

no one can open your wallet if your Private Key is lost, even your own
therefore keep your PrivateKey securely

lose your private key, you have lost all the coins in the wallet
no one can access your wallet, can say your wallet will be lost and its contents, forever

Might be lost for now but not forever  wait until quatum computers become cheap enough for people to buy :)

"Post-quantum cryptography refers to cryptographic algorithms (usually public-key algorithms) that are thought to be secure against an attack by a quantum computer. As of 2017, this is not true for the most popular public-key algorithms, which can be efficiently broken by a sufficiently large hypothetical quantum computer."

Once private key is lost, there is nothing you can do to access the wallet. Always write down and keep your private key in a safe place.

You will not be able to use the bitcoin you have if your private key is lost, that's the same as you lost bitcoin. For that keep your private key in a safe place.

This is exactly why it necessary to always keep a save we record of your private keys. Keys are like your account number. In the visual world or banking system I mean , you can approach the bank to retrieve your account number but as as blockchain is concerned, once lost can not be recovered. Keep it save always.

How to prevent it and what about hot wallets? Can you give me an advice?  Yesterday my PC broke up and I don't know what to do now((

 I think theres no way you can transfer your fund or token if you dont have your private key unless you backup it or you have the jason file...i think the jason file is the support of private key because it will required everytime you create a wallet

As far as I know, there is no way to recover your coins if you have lost your private key. You can try hacking the wallet through brute force method, but I don't think that it will be of any use. My advice would be to forget about the coins and move on.

If the secret key to the MyEtherWallet wallet is lost, where tokens are stored, you can access them using the Keystore file, which is created simultaneously with the generation of the secret key when creating a purse. There are no other options.

 If you lost your private key, you also lost your money i think .Because your money is on your wallet and you have to access on your wallet by your private key of this wallet.any one can halp you to save your funds.you are lost your money.Nothing to do for back your money.

That's the hardest part when you lost your private key, why you should not communicate the staff in what wallet you have. They able to answered you question regarding with your problem. If the email was fully verified hopefully you can retrieved it by password recovery or so ever. This is give lesson to him not only by him i'm talking about us. Because of that we must print private key i a sheet of paper then keep it safe because we are the responsibility who keep our private key safe.

There are hypnotist who claim to help people remember a private key, don't know it's success

You forgot to quantify then when quantum computing does hit the scene on the magnitude order to decrypt it, cryptography (at its current state) will be defunct (even the so-called quantum resistant cryptography which is like closing a sliding mesh screen door to keep a bad guy out) all blockchain in its current incarnation will be utterly worthless so what will be the point?

I have been working on cryptography for 10 years, I see the true gold in blockchain tech, I do.  I have been trying to write an algo for 2 years now that is truly quantum-proof.  The pricinple is the cryptographic blockchain must change when looked at that way everytime it is looked at or accessed it has changed rendering quantum computers and any hacker or government entity UTTERLY useless against it. 

OBVIOUSLY the level the computers are at now-a-days its pointless to deploy this because moving coins around would take years due to computing speeds what they are at now (could you imagine downloading a entirely new blockchain to your computer every transaction at 10000tx per second)??

Just because current tech prevents it doesn't mean the cryptography isn't worth creating, plus its fun if you're into that sort of thing

Oh! this is exactly what happened to a friend of mine. He bought when the price was very low, in 2011 and now he can not find his PK...I think it is a lost cause

If you lost the private key you have  a serious problem bro

if it happens there will be problems because the assets of the wealth and others are in the wallet so if lost can be very harmful so I better copy my private key by printing to paper and save it

If you lost/forgot your private key there is no chances that you can open your wallet again. You are same with my sister her mobile phone got format and all file was gone.

If you lost your private key then it only means that you cannot recover it again since all the missing bitcoins in the market is because of lost private keys and unrecovable passwords from different exchangers so you should always create a copy of it where you can find it easily.

If you lose your private key then there's simply no way for you to get access to your private wallet again. You won't be able to transfer your crypto from your wallet to any other wallet so always keep backup of your private wherever it's possible be it your pc, mobile, cloud, etc .

It is imposible for you to transafer your tokens to other wallet using your wallet address. If you have downloaded your wallet, then use the keystore files to access it. Lost private key is a serious issue if you have stored a lot of tokens in that wallet, so neglegence is you problem and next time be sure to keep you pk in a safer place to prevent loss.

Until now there is no way to solve the problem it, alngkah good if you save your private kay on your PC or phone that you can use when you need it ...

I'm sorry for your lost password, it will be donated in blockchain no one will handle that but will sleep in your address as well. Just let you know that everything that has phrase password are very important..

I experienced that too i accidentally post my private key in a group chat then after a minute my ether and my token was lost and someone took it. But sad to say i don't know who is the one took that so i moving on now but i'm so upset.

Would be pretty amazing and one day it in the future this will most probably be possible

If you lost your key please try to notify, else say by bye with ur coins

True,we are the one who is responsible about our "PRIVATE KEY"  and if ever we lost it or we forgot even single word and number of that we can't access our wallet anymore. I had experienced that one already i lost my private key and i feel bad because the token that my bounty campaign paid me was already on the coinmarketcap and there is no way that i can access my wallet anymore so i should just move on and be so extra careful next time.

Holy shit, thats too bad.

Do you hve Json file ? I am following this post...wish you luck

I think if you forgot private key you can not reach your coins

i already experience that,  i lost my private key, at first i feel sad, because there many coins at that key, i feel bad, but my friends said to me that , dont worry its only the beginning there are more airdrops to come dont worry if you lost it, create again and start ,they said, then maybe that was the time that i feel ok, just because of them.

Professional market analyst say's that, there is a huge portion of bitcoins that is stucked in the wallet and not circulating on the market because some of the owners forget their password or they cannot retrieve their lost password on any exchangers so obviously you cannot retrieve any keys or password if you forget it.

If you accidentally lost your private key that is really bad because you can never recover it.From the beggining that you created your wallet it is already stated that dont lose you private key because you cannot recover it if its lost so you need to make another one.However it is so bad if you hava alot of earnings there.

It could be possible that some bitcoins stocked for that reason. Truly we can say that bitcoin is safe because of it's unique private keys but the problem is, once you've lost your keys absolutely it won't recover anymore. It is very important to have a back-up copy of all your account separate from you have normally used just like PC, memory card or even written in paper.

You will going to lost your coins because private keys is very sensitive that even if 1 character will be lost it will ruin everything in your wallet how much more of the entire keys. I just hope that you are just asking because of curiosity not because you have many coins in it so better back up your keys twice in a safe place so that in case you lost your file you have still a copy.

it seems impossible to help the person who lost the private key.
we make your experience a very valuable lesson.

That sucks.

I am sorry to hear that.

I think I'll go check on my keys now too...

You will not be able to access your wallet, I thiking you will not lose much because only newbies will lose private key.

You are always asked to keep your private key well, it is simply your money. If you lose your private key and anybody finds it, then the person can easily steal your money.

Private key is life, losing the private key is losing everything. Because the person who owns the key can use the key to sign some fraudulent e-mail.Private key is life, losing the private key is losing everything. Because the person who owns the key can use the key to sign some fraudulent e-mail.

There is no solution, the private key to make a backup, this is the only way to transfer the coins, if you are missing, I'm sorry, unless you have other backup, then your coin will always exist where the wallet, Will not be lost, but can not get it.

You will not be able to access your wallet
and all the crypto assets in your wallet will be just a display
can be seen, but can not be touched

If you lose your Private Key you will lose your tokens too, there's no way to bring back you PK if you lose it...
or if you have Json File and you remember the password of your wallet maybe you can get your tokens back... :)

I mean,  how do you can possibly lost your private key which is the important thing to open your wallet, well it doesn't mean any other people can take your tokes,  but it same irresponsible. I don't know of there any other plan which can make another private key with the same address.

A lot of people careless in keeping there private key. Sad to say losing private key is losing your money. If you use coinomi or imtoken it is possible the recovery phrases and private key if you know your password. Better to print your private key safe or print it

noo, that is the worst case ever happen.
except your bitcoin wallet is an exchange wallet.
the most exchange wallet doesnt need p.key to send bitcoin.

If you lose PK, then you lose the wallet, but also on behalf of no one can have your wallet

I feel bad for you. But if you lose private key i think you pretty much like lost your wallet.

Without a private key, wallet is not accessible or coins can be transferred. Private key should be confidential and safe if the private key is lost then wallet can be damaged.

Lost ptivate key is a sad story of our life huhuhu all we need to do is moving on if they lost our private key or hack just never mind just move on

You can access your bitcoin only and strictly only with your private key, there is not other way to access your bitcoins, actually who have the private key can do whatever want with those bitcoins.

    Private key is your access to open your wallet,if you lose it you can't open your wallet,then you can't get also your coins or tokens inside it. You will lost everything that you have in your wallet. But don't worry your coins are still remain in your wallet unless the hacker get it. So,be carefull enough,secure your password and private key. Only you ,can make your wealth safe.

If you've lost your Wallet Private Key so you can't access your wallet again and no one can help you with. Because you are fully control of your wallet,you lost your Private Key means you lost your wallet. Please keep your private key safe and don't give it to others.

Putting a private key that related the letters or numbers on you or if they given you a private key must memorized this then don't lose the this valued things for you. As long as you have a private key you are safe in scammer.
Then if you lose it,. Sorry dude for your lose it is not traceable by admins of your wallet because you are the one who have a responsible on this. There's nothing you can do just forget your balance their and start again a new wallet hoping that next time it wont happen again.

there is another way, if you still keep Keystore / JSON File you can still access the mew and get the private key again. only this can save you.

If you lose your private key to an Ethereum wallet your tokens will be no longer be accessible if you don't have the Keystore / JSON file or Mnemonic Phrase

Or if you accidentally deleted it you could try a file recovery tool

Always make sure you use Meta Mask (https://metamask.io/) to protect your private keys and make several backups of them and store them offline

Better still use hardware wallets like Trezor (https://trezor.io/) or Ledger (https://www.ledgerwallet.com/) to store your assets

Nope it's not possible to transfer your funds... Or if you have your Json file are the keystore file then it is possible to transfer or get your funds back.. otherwise sorry bro nothing to do you have to forget your funds.. and start earning again

If you ever encounter the problem of losing your private key, you should check the downloaded documents that know your private backup key is still stored.

I think you can not even open your wallet

If you lost your private key its the end of your cryptoworld, no one can help you if you lost it
So really really becarefull with private key save it, and you only know it
Or you make 2 or 3 wallet as a precaution

There is no way back. It's sad but that's the way it is.

I think it should be a solution. It is ridiculous that such large amounts of money are at such a risk. A system like Blockchain does not have such a risky side.

We need to be careful especially in our private key, we know its very important thing because this is the only way for us to open our wallet so if you don't want to lose your token just always keep safe your private key.

That is not going to work either, remember when we are holding cryptocurrencies we are completely responsible for our money this is why I think there are going to be many more lost coins once more people begin to get in bitcoin not realizing bitcoin does not have the protections that many other services like emails have where you can recover your account with a phone number, but that is not possible with bitcoin.

If your private key get lost, it is impossible to retrieve all your tokens using wallet address. You must have to be careful not to lost your private key because it is more important than to your wallet address.

If you lose a private key, you can not transfer your coins. This is very important in accessing your wallet without your coins will be forever locked. In this situation you can request mod / dev of a certain coin, if they can help in order to return all your coins from the lost private key. 8)

I don't think that there is other way to retrieve your wallet. Private keys are essential when it comes to our wallet. Without this, we can not access our wallets. It is made like that to secure it from hackers. So losing it means losing all of its content. But if you're talking about ethereum wallet, I think the Keystore File will help you. I just hope you have a copy of it.

Lost private key will be forever lost since wallets are multi encripted, those wallets will be forever lost and will be useless. You can look at the google on how much bitcoins is not circulating in the market because they lost their passwords.

Kiss goodbye to your wallet and any coins that it is inside. When your PK is lost, you can't access it anymore. Also it is impossible to transfer funds from the wallet without accessing it first.

It will happen eventually when everyone has a quantum computer but then the defunct nature of the ever changing blockchain is moot.  The only way this happens is (lets just say I create a string based on Supersingular elliptic curve isogeny cryptography) n²*(Randomization ad infinitum).  Quantum computer looks attempts all cracks at once based on the look... and fails because the base code has been altered after the look.  Success! You have stopped quantum crack... but a continuous attack on the main chains will slow the entire blockchain to a near halt.  It is not efficient without significant advancements in the architecture that surpass Moore's law on the order of 10 over the next 20 years (assuming quantum computing really hits the scene in 2040ish.

Quantum computers for all will step forward before the speed of 0 or 1 machines achieves the ability to do this.  The only way would be to have a singular centralized blockchain with this string that changes.  All transactions would have to occur on sidechains (huge fan of the sidechain cryptos BTW) to prevent attacks on the main block, while the random string runs forever but it would HAVE to be centralized, and no one is going to approve or like such a centralized blockchain... it goes in the face of every reason we want decentralized currency anyways. 

The world banking system will probably employ this though as credit's for replacement of cash as it gives them total control... this also negates the value of other blockchains as they will be able to see where all credits go and regulate every purchase through approvals and denials.  Blockchain tech is the way that they will control everything ... because we can't get unified behind one and no one is smart enough to make one the Grand Unified Crypto... we have sped ourselves toward the ultimate control mechanism.  Its funny that the system we wanted and created will be the undoing of everything we were trying to achieve. 

Who is John Galt?  Who is Satoshi Nakamoto? Same story different author.

As i remember(i've read instruction for myetherwallet) if you lost this key,you can't recieve access in any case!

If you decide to invest, do not delay and start right now.

I think the developer will not entertain this type of problem as this is cause by the negligence of the users. Many had reported lost private keys and their coins will be in trap with their wallets and considered lost forever. In doing cryptocurrency the most important thing is your private key, you should keep it in a safe place and always provide a back-up copy.

Not relevant answer to the OP,he is talking about private key.

Do you know what is a private key?

It is like a stong password will be given at the time of creating our wallet so we need it always if we want to access our wallet.

as far I know, no one, even you or the service admins can access if you lost your Private Keys.

Yes thats pretty much good as gone. Is there a way of accessing accounts if you loose the device your google 2FA is activated on? and can you change over to another device if you loose the 2fa retrieval code?

Without your Private Keys, you're pretty much screwed. Make sure you look after these and keep them very safe, secure and do not share with anyone.

I do not know how to solve it, because if we lose the private key we lose everything we have on the wallet, MEW also said that can not recover the lost account Private Key, so I suggest that you print it and save it in place safe, and always do backup data regularly

Normally, if you lost your private key, then it means you lost your coin(s). Just like a common joke here; if you dont have the key, then it's not yours!  ;D
So, be careful when keeping your private key because it's so essential.
But if you only lost access to wallet but still have your private key, then basically your coins is still there. Just use regular Bitcoin wallet and you can restore it using your private key.

If the key is lost, then there is no way back because the block system is not designed to support such a system as losing keys and moderators will not help you either.

If you just lost your private key but still have access to your account then yes you can still transfer your coins. If you forgot your password also then you really have very little to no chance of getting your coins. Always have backup plans when it comes to investments and money.

Even admins can not access the wallet. Private key only know by one person not include the admin or the dev. That's why we must save the private key when open new wallet in the safe place and any place.

You have not lost your private key you can get it back.Go to your downloads search for your UTC or  Keystore / JSON File,you can recover it with this but you will need your password you used in creating the wallet to achieve this. I have recovered all my lost keys with this.GOOD LUCK

there is two option in accessing myetherwallet, thru private key and json file.if you lose your private,the other way to open your account is thru your json file. if you lost them both,then sorry.there's no way to open and recover account in mew. those are very important things you should keep very well. you must have it in printpaper so whatever happen to your gadgets,you still have your private keys.

If it would be possible without private key we would all be sending bitcoins from the top addresses right?  ;D

There's a way in recovering your Private key if it is you key to your myetherwallet. But you should have downloaded the UTC and you still have the password when you create your account. I have lost my PK before but i recover it again.

this is one of my nightmares, do not let you experience it. especially bitcoin investors, who forgot to put or lose your private key.
because if that happens, it's just like you lose all your assets, and do not ever expect it to be back!

I have a friend lost the password from the blockchain, and there are not any data any more, the campaign of his bitcoins went to those 5 millionths that are lost without a return, on the one hand it's cool that neither as hack, and on the other hand it's sad that do not restore the purse with coins!

Keep your private key safe at lest in two different places because once lost your business with that wallet comes to an end, you can only view your wallet with wallet address and can not move anything from it so be careful.

Cryptocurrencies are very unforgiving about this, once you lose your private keys it's over you cannot recover that money, this is not like bank accounts where you lose your password and you can always get it back some way or another, once you lose your private key or your seed words then there is nothing to do that is the way bitcoin is designed and that is never going to change.

if you lost your private key there is another options that you can access your account just like JSON file, but if you only save private key and you lost it, that you cannot access your account say bye bye your all tokens.

Does your private key lost? Thats not a good news for you. It's is very important to have your key. What kind of wallet are you using? If you use myetherwallet, there are one option you can do (if you download it). Json can he download as you print out or write your private key. This is another option so you can open your wallet. It's like a backup if ever you forgot or lost your private key. If about bitcoins wallet, I have no idea how you will retrieve it, unless if you tell your beneficiaries about  your private key (to the one who will inherit in case something happens to you)

If private key is lost then your altcoins holding will also lost forever, that is very sad  :'(,

I don't hear this kind of problem before has been solve.  :-[

after we get the bitcoin or altcoin we keep it safely in a certain wallet so that others do not know the key, and do not get lost or forgot ,,, if the private key is forgotten or lost then all the coins we have will automatically disappear as well.

Yes it is true, when we lose the private key then it certainly will not be solved, this must be important for us all to always back up important data in some places, do not just rely on one place because if lost then we lose everything .

The private key is such an important thing. No one can help you. The only thing that can open the wallet is to use the private key. Is there more than one currency in the private key? I also feel sad for you. I remember backing up the next time, brother.

If you lost your private keys then its impossible to get your coins back. If you still have the computer that stored your Bitcoin, there’s a chance to get your coins back. This is under the assumption that your wallet file is still intact.

That is why we have be a responsible for keeping our private key safely. Because our private key is very important. We can not access our wallet account if we have lost our private key. So in order to prevent from lost private keys.. We have to puts some back-ups its either we save it from the USB or the personal loptop for assurance that in case we lost our private key, we have a back up.

losing the private key is just the same we lose all what we have for ever because lost our private key can no longer to access our wallet so what we have been buried for ever

Bitcoin Personal Keys are very important. If someone leaves his wallet, he will lose all his coins. So work with caution and keep your personal key in custody.

Unfortunately, you won't have access to your tokens the moment you lose your private key. So be sure to backup your private keys please. Make a QR code and save it somewhere else and multiple locations.

if u can access to the wallet and manage your digital coins then you are safe, it depends from which kind of wallet you are dealing with

Lost private key means lost of money and there's no way to recover it again without your private key and UTC key. In order to avoid it happen again you must have at least 3 option to keep your keys safe.

My friend how so sad that you lost your private key.I hope next time you keep it in a right storage because this is the most important factor that you can generate an income.And then when you lost it you will never trace you wallet anymore.Be responsible always my friend for the next time.

A private key is used to sign your inputs and outputs which are the part of transaction. Without your private key you can no longer prove that you are the owner of these inputs. That is why storing your private key or seed is very important. Many people ignore that and they later blame Bitcoin for their mistake. Some people prefer making multiple encrypted backups, some write down their seed on the paper. There are also people who engrave their seed in the steel in order to make it fire and waterproof. Buy a hardware wallet if you are really paranoic.

Yes but that is only possible in case of Etherum. Myetherwallet gives you number of ways to access your account. But for bitcoin private key is the only way to access your wallet. You can also restore your wallet with the seed but i am afraid if these are lost there is no way of recovering the bitcoins and those bitcoins are lost forever.

Spend your evening drinking Jameson and next day will bring you new opportunities=)

if you have file name UTC and password it's easy

Yes, because no one can open up your account if you tried to lose the copy of your Privacy key. It is very important because it is the key in able for you to access your accounts and secure it. Try to look other opportunities and try to mine bitcoins. It will help a lot. Invest in other crypto.

That's how bad when we lost our private key.  Because we can not access our wallet account if we lost our private keys. So in this case we should always remember our private keys. Its better to memorize it in order to keep it safe. Because if some one found our private keys and they already know how to hacked that key. Then for sure our wallet was empty.

There will be no way to access your wallet anymore. Losing a private key means that you lose your account permanently

it's hard to lose a private key especially that it's a lot of wallet tokens, it's no hope that you can open the wallet again because you've been neglected.

Correct, with the keystore file you can use it to access your wallet and you can get your private key again. If you only had private key and the keystore file is gone you can't get your private key again if you lost your private key. That's the time that there's nothing you can do and create new one and the old wallet with tokens will be gone or out of reach anymore. You better save the most important with the wallet, the keystore file utc/json contains your private key that is encrypted with the password you provided when you create it. Hope it helps.

For bitcoin private key is very important. If someone lost private key of bitcoin it is very hard to recover. One thing can prevent from losing private key of bitcoin. User of bitcoin should kept the private key either in safe hard drive wallet. But hard drive wallet can loss accidently. It is better to keep it in online safe wallet.

There is a way.....
use any programming language and code iteration of alphabethical and numeric sequence to find the exact account number.
This is the simplest way and no need for any degree, just knowledge in programming language, and of course, Time, Electricity, Idle hardware (good one), and some candy (No rice! or Meat! Especially Beer!!! Bad in waiting situation and condition). And remember to get your wife/husband (and children) away from this computer!! Especially if you find that they go near this computer with pure intention of horny or unsettlement self muscle contraction.

If you lose your private key, whatever was stored in that wallet cannot be recovered. The entire security is based on the fact that private keys cannot be guessed or recovered. Sorry bud!

Your privatekey ei very important if you lose your privatekey isad tobsay that all of your token is never recover  the best way to keep your privatekey is to write in paper and keep it in safe place ..

Nothing you can do if you lose your private key.

If you lose the private key then the solution to restore the wallet is the JSON backup file, this file in the process of creating a wallet if you save it will be able to restore the wallet without having a private key :))). Once you lose both the private key and the JSON file recovery, no one can help you recover the wallet

Satoshi have a saying about the lost keys and he says that it would be a gift to the whole market as no one could access the wallet and they would be untouched so the possibility to dump the btc would be zero

well the only thing i had in my mind in order to recover your lost private key is wait for the future
there will be quantum computers in the future that can calculate a million times faster than an average laptop
if that kind of technology became available to the public then i think there will be a chance that you can recover your private key

i believe in the quote that
there is no treasure that can be hidden forever that's why it only needs to take time to find a burried treasure

Private keys are very important. Once you lost it you cannot recover it and you will lose all your funds. You cannot transfer tokens either because once you lose it you will no longer have access to your account. It is recommended to keep your private keys in safe place and always make a backup like print it in a piece of paper then keep that piece of paper in a vault or save a copy of your private key in your flash drive. All of your funds will be just a waste if ever that you lose you private keys. That's why you must always take care of it. Don't blame the wallet if you can't recover your private key, you are the only responsible for it. If you lose it, it's because of you carelessness.

There is no other way to transfer the tokens on your wallet.
So keep the private key as it's the only way to unlock the wallet again

I think you can not do anything without a private key .. for this reason I think it's good to know that if you lose your PK you lose money.

In order not to get into a very unpleasant situation when you lost your private key and lost all your money - make backups, or write down your private key in a notebook.

Once lost, it is hard to be recover the keys. Private key is more important thing that need to keep on you to access your file. It is better that you know where to keep it because not all account can be recover. You have to be careful and make more backup of it because you can lose everything what you've gain if you become clumsy on it.

i already experience that, i lost my private key, i accidentally deleted it, if you lost your private key, you cant access or open you ethereum wallet, you cant sell your token in any exchange , in short your wallet is gone if you lose your private key.

If you lose your private key, your encrypted currency will also be lost, because the private key corresponds to your encrypted currency, which is the block chain technology.

No this can not be happen. Look if that can be happen it will be easy to other people get other's token by using address  ,you are the one who responsible to keep your private key and if you lost it then your token will also be lost.

If you are talking about your eth wallet private key no. You can't retrieve it and its possible that if someone sees it, that person have the capability to get or transfer all your tokens in that wallet. As private key is also like password you should have backed up it to a safer place. That's the bad side in having eth wallet if your a forgetful person..

Real wallets can be taken back or used by someone else. The crypto wallet will be lost forever, no one can use it

sad to say that your coins will lost forever too if you lost your private key. if you create a wallet you should always make a back up of all the information created for a certain wallet

if you lose your private key then you can not transfer or you cannot recovered your private key, it's really important that we keep the private key. when the private key is lost all your earned token coins are lost forever. it will be worthless

Some types of purses use many private keys hidden inside them. If you only have a private key backup for a visible Bitcoin address, you may not be able to recover most of your money with your backup.

That is really a big problem if you lost your private key plus you don't also have the backup or mnemonic of remember it. Much even worst if that crypto wallet has lots of crypto assets that worth millions.

I am afraid you can not transfer your coins into another wallet since you have lost your Wallet Private Key because you must use that Private Key to open your wallet (if Private Key to be use to open your wallet) . How can you transfer your coins if you cannot opened it? So, please keep your Wallet Private Key safely.

Never lost your private key because you will lost also your account. It is big lost because all your tokens and coins will be lost and can never be recover again. So, you better keep your private key safely and don't give the private key to someone else for privacy.

Oops that is so wrong.
You can't recover it anymore as long as you can't remember or you don't have any back up.
That's the important thing- private key. sorry for that, but hoping you can solve it.

That very very hard to open your wallet there a way to open your wallet is to brute force using software only developer can do that and you have to pay for them to open it and besides it take a long way to open it if your not lucky it will take years to open your wallet.

This is the thing I hate, losing a private key is a ridiculous thing and before that happens then we have to do everything for example back up data, print out, save on Google drive, or other cloud data, never store in one place, it will make us regret.

One great feature of cryptocurrency is that the wallet address is tied up with the private key. You cannot transact one without the other.  Not unless you have your computer saved a cookie for it or have the json file intact. If not, I think there is nothing much you can do about it but to create a new one.

a total of 21 million bitcoins can be produced, and not one less is a strict limit to which their number will gradually aspire. Did you know about this? Is it true?

Losing your private key means losing your bitcoins. There isn't anything you can do after that. No one in the world can recover your bitcoins than. They are lost forever.

I can say that "better luck next time"  ;) when you get lost your private key of your wallet address there's no way to retrieve your tokens, but if you have the JSON file of your wallet address you still have the access to your account and get to exchange your tokens  :)

This is the reason we have some coins missing in circulation. Once someone lost his private keys, that coin is gone, true. I don't wish for such.


Mate, if your question is because you lost your PK, I'm sorry you might be able to get a solution from a third party. All solution is with you, that is if you can still find it. The more reason we shouldn't treat our wallet as just a novel that we can replace from any shopping mall. I wish you well.
This is the reason we are having some coin missing in circulation because people can't recover their private keys and coins keep getting reduced daily.

If you lost or deleted your Private Key especially on your PC, maybe last hope is try finding it with file recovery software like " Recuva " to recover your lost or deleted Private key...
But if you still cant find or recover it with file recovery software, Say Goodbye with your coins, because there's no way to recover it again...
 :'(

NO! Plain and Simple. There is no way to recover your coins if you lose your private keys. End of story.
Hence, you should be extremely careful about storing your private keys. Ensure that you upload it on some secure server or keep it in a flash drive.

It is better for you not to think about it cause you can never access your account anymore.
This a big problem in using blockchain technology,  and I know a lot of have lost their private key which the code needed for accessing our account. That's why we should be very careful with that, keeping it safe and have back-up copies is the only way we should do.

Sorry for you dude. No matter how much you lost, it is always sad. But whenever you feel sad about losing your private key, hence losing your holdings, remember that Satoshi Nakamoto himself lost private keys to a total of 1,000,000 BTC.

If Wallet Address alone can really transfer token to another address, I think all of us here in the crypto world is already hack by the hackers.
If you forget or lost your private key. You are really in bad luck because, you can longer access your wallet ever again.

Unfortunately the loss of a private key means losing access to your wallet, so if you lose the private key you will never see your coins again.

Oh real mistake, probably lost private key means losing all coins. You can't access your wallet it means Back to zero .Its like losing your efforts and hardworks but theres a lot of time to recover unfortunately a bad time for you but I suggest you to dont lose hope great things comes in great time.

if the private key is lost then you do not have access to your account yet and you will not get your bitcoin or the money you have in your account.

Absolutely, you can never access it anymore.  Losing such key is gonna be losing all the hardworks you have made. It is really a big loss for you more than a loss in gambling especially if all your earnings are still there.

Lost private key is lost all your crypto relation about ETH

I only use json files as main, and privatekey for me is dangerous and most of me back up this file a lot of places. If it's MEW, it's a way for you to access the wallet and switch transactions easily. You should have a place to back up the private key. but as I say. It is very sensitive to anything.

This is extremely common people do not have backups and then when they lose their wallet they have no way to recover it, it is my opinion that you shall have backups you should even have backups of the backups that way no matter what happens you are not going to lose your coins this is especially important if you're holding an important amount of bitcoins because you never know what kind of value bitcoin is going to reach in the future in a decade or two.

Unfortunately,you can't get access to your wallet, so say goodbye to your money(

There are a few  Key Recovery Services (KRS) that you can look into for whichever wallets you currently have access to. If you Google "Key Recovery Service bitcoin" you can find projects on Github as well as some paid services. I'm not sure how well the ones offering actual "decryption" function for wallet/private key recovery, but you can do your own research.

We're actually developing a KRS solution that involves multi-signature and biometrics such as facial recognition.

It was very sad to know that lost private key's are not recoverable anymore because there are a lot of people today who are really old and they need to pass those keys to another person in order for their coin to be inherited by their family and to be useful.

Your account will still be active and coins might still be sent to it, thing is that you might not be able to log into your account and access your coins,its also unfortunate that a lost key cannot be recovered.
