As a new in bitcoin researchers which is good Mycelium or Electrum? I want to use a best bitcoin wallet. No hacker's can't be hack my wallet. So just from my curiosity which is better bitcoin wallet. Very high security wllet which? Need information

Both of them are having the same principle of working that is by using the "private keys" itself. One thing is sure about them that, both have the security measures uptown the mark. You can have initial password to both of them and later your private keys are master codes for accessing the wallet. So I believe both of them are good to go in long run.

As you are using private keys to access the wallet, the security is actually in your hands and how much secure you keep your private key.

About Ethereum : Make sure that you use the upgraded version of it, as previous one had some vulnerability.

I suggest you to use Mycellium. I used my Mycellium in my android phone as a bitcoin wallet before I switched to coins.ph. It is really secured,  Im telling you because I've tested it. It uses 12 words as a private key if Im not mistaken. But electrum is a secured wallet too, though I haven't use electrum yet,

I mean both of the wallets have different use factors, as electrum is something which can be used on your desktop and mycelium can only be used from your smartphone. SO they're going to cater to different types of people with this use factor. I personally think both wallets are fine, even though I do personally use electrum on my desktop with 2FA.

Depends on you bud.

I'm using Electrum and feels pretty good.  Although it has just been discovered that there are security hole, but the developers have repaired and upgraded it, I still believe Electrum. It's important that you must hold the private key, set the password for your electrum wallet. However, it can still be hacked when your computer is infected with viruses or hackers are invaded. Better, check your computer regularly, do not visit malicious sites to ensure your computer is not compromised.

I've never used mycelium, never had to. I somehow came straight from running a full node into electrum because the node was preventing me from sending quick transactions. It was always a 10 min wait before I could check how much coins I got, while with a light wallet it takes maybe 10 seconds.
Electrum is getting frequent upgrades so every time something nice is taking place (like segwit) electrum is right on top of that. I think it was the first wallet that allowed you to send segwit transactions. The only problem they had was that recent security flaw, but they were quick to repair it. This is a great reminder that you just can't download something and consider it unbreachable. You have to keep it up to date because shit happens ;)

I think Electrum is the best desktop wallet but need to regular update.Its the safest wallet but few days ago we heard a news Electrum hack so first know and research so you can visit also https://github.com/spesmilo/electrum-docs/blob/master/cve.rst

Since that scare that was up on bitcointalk about Eletrums security flaw I am very reluctant to use them so I stick with blockchain.info.
I just like how blockchain.info looks and works. Very clean and nice interface that gives you lots of information and the value of your bitcoin too.
Electrum I use to use and did like because it is safe. I bought a hardware wallet because I am not going to risk that many bitcoin.

I think both wallets are equally good but have different usage factors, because electrum is something that can be used on the desktop and your mycelium can only be used from your smartphone. So they will serve different types of people with this usage factor. I personally think both wallets are fine, although I personally use electrum on my desktop with 2FA. essentially yah it's up who want to use it. but I personally use electrum.

both are good .i think u can use both and remember to use 2fa  :)

I'm using electrum wallet for the past two years and I could say that it's one of the best wallets to store bitcoins. When you download the electrum wallet, better download the latest 3.0.5 version since it's safe. Download it from the official website Electrum.org and not from any other fake websites.

i'm sorry but that doesn't make any sense!
the worst desktop wallet is a lot better than any web wallets. and Electrum is like one of the best desktop wallets. besides the vulnerability was simply blocked if you had the simplest password! not to mention that if you talk about ways to lose your coins when using a desktop wallet, this vulnerability is near the bottom of that list. the risk of you having a keylogger or simply one of those clipboard hijackers is much higher and it is much easier to steal your keys that way.

and blockchain.info which you mentioned here had some serious issues. need i remind you of the usage of random.org for generating private keys by BC.I?

Electrum has Segwit support (native segwit included), while Mycelium doesn't plan to, for the foreseeable future, so it's a no-brainer to go with Electrum if you want lower fees.
Of course if you do not want a PC or use a desktop wallet then you can go for Mycelium, or better still, a mobile wallet with Segwit support, like Samourai, Greenbits, GreenAddress, etc.

As a good decision both are best/better wallet, sometimes we use a normal wallet as coinbase, blockchain etc. But both wallets is so strong and high security. Someone use Mycelium and someone uses Electrum. I knew a extra wallet thats name Jaxx. It also preety good. By the way try for Electrum. Best of luck.  8)

If you want security for your coins then I can say you that not one of your choices will not meet the security criteria you are looking for.If you want best security wallet for store your coins and everyday use then nothing but hardware wallet(Ledger,Trezor,KeepKey) is out of the question.If you just want to store you coins for some time then paper wallet is good choice,also cold storage could be made on PC with no connection to internet.

If you use online or desktop wallet you will never have a level of security that you are looking for,buy hardware wallet and sleep peacefully.Otherwise you can wake up one day and open your wallet with 0 balance.

Two factor Authentication is the best way, I know. But Its hard when/by any mistake if I lost my 2fa code, then it will so bad. So I want a wallet which is good overall transactions fee low, fast more secure. By thr way, thank you for your valuable reply.  :)

My suggestion is for mycelium,this wallet contain of words before you can log in to make a higher security in your money.Although it has a higher fees or charges when transferring,this is best for smart phone to restore .

Electrum will suit for your needs then, mycelium doesn't yet supports/has implemented segwit. with segwit enabled on electrum you'll be able to send cheaper transaction compared to legacy wallet. regarding 2fa, you can always backup your 2fa keys and or use 2fa apps like authy which saves your codes in cloud.

Why not do a dry run and test them alone? Test them for a couple of weeks or months and see for yourself on what really suits you?

I like electrum because its lightweight and easy to use but I have nothing against with mycelium too because its also reliable so both are a good choice.

But if you truly want a very high security wallet, I'll go with hardware wallets.

I would agree with this. If security is your first priority then go with a hardware wallet like ledger nano s and you also use it with mycelium.

If hardware wallet is also in your consideration, it's better with it. That's the most secure one.

There is also trezor but the most preferred wallet of majority is ledger nano s but I've seen people here that they are using their spare laptop and installing electrum them and treat it as their offline wallet which is also a better way to keep your bitcoins.

For the record, I just downloaded Electrum and it seems to have a very healthy number of security options, one of which includes 2-factor authentication. While I did not use this because I have other security measures in place, I do recommend you take a look at it. It supports SegWit addresses as well for lower transaction fees and it has a clean user interface. I have not tried Mycelium personally, but I might get it on my phone on the near future. As of now, I cannot comment on it, though. From what I have heard, either should be fine and it's up to your personal preference.

Using an old laptop means there will always be that little chance of some malware being there. Even if you format it and install Linux, there can still be some malware. Some paranoid people might say to avoid doing that.

that is impossible to have 100% secure wallet and only you that can make your wallet safe. so far, I still use both wallets and I don't have any problem with both wallet and I can suggest to you to try mycelium and electrum at the same time. but I really like with mycelium because we can choose the fee that we want to use when we want to send some amount and I think the time is not taking too long to see the amount is arrive in another wallet.

Uh, no, not really.

If you install a proper public, stable Linux distribution in a laptop that has been properly formatted with no hidden partitions or anything of the sort, then you should be fine. I see no way that your wallet could be compromised by malware in this way unless the malware was delivered as part of the operating system and made to delete your wallet rather than send it over, as all network interfaces should be completely disconnected making the attacker unable to steal anything. I ask of you to explain how it would be possible.

I'm not an expert with linux since I'm a windows users.

What is this malware you are talking about that even the simplest way of killing them which is formatting will make them remain in the computer?

AFAIK, linux is a virus-free OS since its an open source and its not a preferred OS by the majority. Are you thinking that those malware are sticking to the hardware of the PC?

Yes please, I'm interested of knowing that part too.

Careful there. Your understanding of Linux is a little off, which is not good when you are wanting to stick to a fully secure system. Linux refers to the kernel of the operating systems that use it. The actual operating systems vary and include Ubuntu, Debian, FreeBSD, CentOS, etc. Unless the computer or component manufacturer were to stick a hidden network card which somehow connected to the internet without any user input or knowledge, it is highly unlikely that there is a hardware-based attack vector for stealing wallets. At the most, it would delete them, which would net the hacker absolutely nothing. It is simply not possible that after a proper format of a hard drive there could be any malware left. The malware cannot just spread to other hardware pieces as the person you quoted seemed to imply.

Hi btcton,

Thank you for clarifying that thing. As I stated I'm not that knowledgeable that much with Linux and I appreciated your correction with the thing that I've said.

Loving the forum with people who are more knowledgeable with the other fence that I'm not good with.

You're more than welcome. I simply do not like misinformation being spread around the forums such as was the case with what jtipt said. He also never came back to clarify at all, so I kind of felt forced to chip in, since what he said was simply wrong. What rubs me off is when people claim things they are not fully knowledgeable about as fact, but I can also just assume that he meant to say something else that I didn't quite grasp. I may not be the most knowledgeable person regarding the blockchain technology and cryptocurrencies, but when it comes to computer systems, I am overly comfortable with them and know a good amount as it is my job, which is applicable to most applications that are related to crypto and security.

A laptop will quite a bit of software in it even when you've erased the drive:

There's BIOS/EFI. Any operating system you install will at some point be interfacing with this code.

The hard drive controller has a CPU running code in it. Perhaps it has malware in it that looks for sectors containing wallets. If such a sector passes through the controller, maybe it alters the seeds/keys/addresses. This would be operating system agnostic.

If the laptop has WiFi and Bluetooth, that's two more processors running their own embedded code.

Keyboard controller. Trackpad controller. Power management chip. Even batteries may contain a CPU.

Almost everything on this list can have reprogrammable "ROM" these days. If there was ever malware on the computer, how do you know it didn't leave something behind?

Well, I notice this is an interesting question. Are there cases of malware spreading between the resident processors in a modern computer system?

Note. Let's not seg over to trying to refute the irrefutable hypothesis here (EG "Well can you prove it couldn't happen?").

This is a straightforward question. Should we be worried about malware spreading between subsystems in a modern PC?

First time of noticing your personal text of being a sysadmin that's why hearing words from professionals like you is a big blessing for an aspiring computer systems tech like me.

It's like you are giving free advice and tips through the entire forum about security which is related to the topic of choosing desktop wallets.

He didn't comeback to clarify what he said about the old laptop containing some malware. It's inevitable but it all depends to the user on how he is tech savvy and good from keeping himself with such malware and clickbaits.

Sorry, did not see this until now.

To answer the original question (codewench), I think you are missing the context of the original post I was referring to. We are talking about a device being used solely for the purpose of holding coins as a cold, offline wallet. That means all network devices would be disconnected or in some other equivalent way disabled. Without these hardware components, there simply cannot be network connectivity in any form. The only other memory that could hold a significant amount of persistent storage would be the BIOS which would have to be intentionally flashed with the malware-infected version while still be signed by the original manufacturer. This is incredibly difficult to accomplish for obvious reasons and even if a hacker did try to do this, they would still have no way to actually contact back their own servers since there is no network connectivity. The only attack vector I can even think of is a variant of ransomware with a pre-stored encryption key to which only the attacker would have the decryption key. But we have already ran way past the plausibility point, so it is mostly worthless and purely hypothetical.

I used mycellium as my mobile wallet , easy to use and comfortable.I dont have laptap so I use my smartphone and restore mycellium as my wallet ,charges are low when transferring and it has a key words that make others hard to  detect or hack my money that I store on it.

Both are good wallets but my choice would be Mycelium. It suits me better and it's more convenient because it's mobile wallet, security features are good.
Electrum had recently some security breaches and issues but that doesn't have to be deciding factor.

Both mycelium and Electrum are best wallets to use.  Mycelium supports only smartphone while Electrum supports desktop. Both are using private keys. I supports Electrum is supports 2 factor  authentication with low transaction fees and with high security. It uses Segwit address for transaction. It had clean user interface tools.

A lot of my bitcoin friends are using Mycelium, so I guess it is majority wins. I would probably use it too!

I am familiar with Electrum wallet as i am using it. I am yet to use Mycelium wallet. I started using Electum wallet for Segwit. The transaction fees are very low. Though current transaction fees are very low, it used to be more during December and January. The features are very friendly. We can adjust number of blocks to reduce and increase the transaction fees.

Both wallets are working under same principle that is using private keys. I would prefer Electrum wallet, because this wallet has Segwit enabled. This wallet is very safe and secure, while transaction fees is very low. It supports desktop and mob android as well. In this security options include 2-factor authentication. This is user friendly and transaction speed is very fast.

Many of the crypto users have recommended electrum, so there's no doubt that electrum is the best among the other good wallets. Take care

Electrum wallet is the best. It is based on private keys. The security level is high and Electrum wallet is safe to use. The transaction fees is very low compared to other wallets. So many users prefer Electrum wallet rather than mycelium wallet. It supports 2 factor authentication and it is also supports Segwit address for low transaction fees.

Mods please note, copy-pasted message to harvest post count.

According to me Electrum wallet is the best. Iam using it for long time. Iam using this wallet for segwit. It uses two factor authentication and private keys is an additional advantage of this wallet. This wallet is very safe and convenient to use. Compare to other wallets the transaction fees is very low. It supports both android and desktop. The security level is very high in this wallet. The transaction speed is very fast than other wallets.

I have used Electrum and i feel very secure in using this desktop wallet. Twice i got my computer hacked but god grace they were not able to crack Electrum seed key. And it is very light to use their is no need to download full nodes, just download the software and key in the seed key and your wallet is ready to use.

Yes, I support electrum wallet.
Its great wallet and so more secure than all other wallet.
I used it, good wallet without confusion/doubt.

don't forget that when you are using 2fa in Electrum you will be charged for it!
many people do not read the fineprint and then wonder who the hell charged them 100k
it happens that Electrum uses a third party 2fa provider that charges 100k satoshis for 20 credits aka 20 uses
so if you are prepared to pay for 2fa-be my guest,but I think 5k for each login is slightly overpriced and unreasonable

Then you don't understand how the 2FA system in Electrum works... it is not a "login" 2FA system. It is a "MultiSig" wallet that uses TrustedCoin as a signatory. They will only sign if you successfully complete the 2FA process. So, you are only "charged" for each transaction that you request TrustedCoin to sign.

You can open and close your wallet as much as you like without being charged. Additionally, you can get your funds out without having to pay ANY 2FA charges by disabling the 2FA functionality (restore from seed, select "disable" when prompted).

I do have an experience with only Electrum. A good experience on Segwit with Electrum. The transaction fees was so minimal which event did not cross 2 dollars.  It has been so supportive during December 2017 when the transaction fees were so high. The transaction was so quick and secured. Electrum system is setup with friendly configures.

Electrum for desktop. Exodus, although not open source, has been around for 6-8 months without any major issues reported. It has a more user-friendly interface than Electrum. On Mobile, I've been using Eclair wallet lately and would recommend it.

Iam using Electrum wallet for long time. This wallet is safe and secured for using. The transaction fees is very low and the speed is also high compared to other wallets. This wallet is based on segwit so there are so many bitxoin users use this wallet for their transaction. It supports two way factor authentication. This wallet is used in both destop and also anroid. The configuration is so friendly for its users and it is based on private keys.

I think both are good and could be recommended but my choice is Mycelium. I use it for a long time now and it has good qualities in every way regarding safety, user friendly features, transactions fees, full control of private keys etc.
Here in case of these two wallets it's more the question of personal taste than some differences that decide in favour of one wallet or the other.

I used electrum, pretty good wallet

Yes both are good wallet but most are using electrum and I'm one of it. I've been using electrum until I got my nano s.

If someone is still confuse on what to choose, try both of it or see the comparisons of other websites.

https://www.reddit.com/r/Bitcoin/comments/6qk8fo/is_mycelium_safe_or_electrum/

https://cryptocolumn.com/mycelium-vs-electrum/

Mycelium and Electrum both are good wallets. Compare to mycelium Electrum has more features. That's why many people choose their choice as Electrum. Iam also using Electrum wallet for long time, still now i dont face any problem in this wallet. This wallet is very safe and secure wallet with user friendly options. It enables segwit address for low transaction fees. It is also based on two factor authentication and private keys.

both mycelium and electrum are good and I won't say the best bitcoin wallet but I prefer with mycelium although in the past I use electrum too and multibit to save my bitcoin. mycelium can install in your android phone so you can transfer your bitcoin in your phone, I don't know how about electrum and maybe electrum is available too for your android.
