Blockchain have more than 8 millions users !!! There are some nice security measurements inside Blockchain - 2 step verification, second password and advanced settings like - login IP restriction, block access from TOR etc. How to better protect Blockchain wallet and your wallet funds ? I think only advanced settings - like login IP restriction, block access from TOR, password stretching etc. really can help.

Yet most people would still run the bare minimum for security and most likely would not be interested in upgrading their protection in any way.
Think this is the one wallet most new users end up connecting to and then if they stick around they branch off into other wallets.
My main gripe with them is they can go down infrequently and the last few times where when I need access to the funds,so now I am more spread out to protect myself from being all in.

Still need to figure out the new wallet as I was a slow adopter due to a old computer,now I need to learn the basics all over again,like signing a message!

I do like the features and it shows that they are trying their best to secure the wallets in a more effective manner,its up to the customer after that.

Important thing is to always have a backup of your wallet AND private keys.

Also don't keep all your funds on an address connected to your online wallet. Regularly transfer funds to a Paper Wallet/Cold Storage and you'll be fine.

Where your source blockchain have more than 8 millions users?

I don't know why people still choose blockchain wallet for storing their coins, although just a dust, but a lot using it for storing all coins and mostly don't know how to export/backup their private keys.

To secure blockchain wallet is, move balance to better wallet.

Yes IP restriction, blocking TOR access, enabling 2FA authentication can really help but at the end, it is for securing wallet and not the blockchain. Since I have seen news of many exchanges got hacked, I don’t take any risk and thus maintained a cold storage to maintain maximum security (even my family members don’t know about it), I use blockchain mainly to transact and monitor my bitcoins and not as a main storage location. 2FA with mobile OTP is best  way to keep blockchain wallet secure.

1.Blockchain and blockchain.info two separate things.
2.Provided they have taken all the possible security measures,hackers are always one step ahead of them.
3.Storing coins on a third party wallet is never actually your own wallet.
4.I agree,for daily transactions blockchain.info does serve the purpose but like every other bitcoin noob first step is to import your private keys and paraphrase,wallet identifier too.
5.Having said that,there are zero ways to recover a lost password account on blockchain.info.

you shouldn't keep large amounts of bitcoin on an online wallet and you should keep less on a web wallet. if you follow this simple but important rule then there is nothing to worry about when using blockchain.info just do two simple things:
- use a strong password
- enable 2FA

On line wallets are never 100% secure. For long term storage of large amount, cold paper wallets are actually the cheap and best choice. Just make sure you create them correctly and import the private key into blockchain wallet when you need the coins. Keep coins in separated addresses so that you won't lose everything if one is compromised.

Why'd you use a cold storage? I find it quite stupid if you need to use it daily. Some users keep like 1-2 BTC online and the rest on the cold storage. It is indeed the best solution, however, it is a pain in the ass.
What I do is simply check my computer for malwares. I can say that 95% of times that someone loses cash is because of a poor security. I must say that I have been hacked, luckily the idiot didn't steal me a lot, but it was because I was pretty dumb.

All-in-all, just don't execute random shit online including but not limited to generators ("Bitcoin magic generator, earn millions a day") and bots.

when i first started out in bitcoin blockchain.info was a great help but as i learnt more about bitcoin security i moved to paper wallets for the majority of my bitcoin.  i think it was just after i read about a bug in blockchain.info generation of key pairs which allowed alot of bitcoin to be swiped.  i think the guy that took the bitcoin offered it all back in the end as he was just wanting to show it could be done.

i think you are thinking about paper wallet when you say cold storage, but cold storage is a wallet which has no connection to internet and never have and never will!

so the solution is simple either use an always offline PC like an old laptop or use a live linux on a USB with persistance and install the wallet there. it always remains offline and you can spend whenever you want from it.

2 Factor Authentication goes a long way if you want to add security to your Blockchain.info wallet. I would also recommend blocking Tor logins and activate the second password. Other than that, there is nothing else you can do except to secure your PC well.

First of all, you have to change the word "Blockchain" into "Blockchain.info" because they're different.
And btw, why did you use the same sentences twice?

Anyway, here is my answer to your question.
I think the best way to do it is just by using all of the security features that has been provided, and also don't ever let anyone have access to your email.
Because if anyone has the access to your email, that means he also has the access to your wallet.

Of course, since in your online wallet you are not keeping your private keys. Also, any moment , the onpine wallet can declared being hacked etc. In my opinion,among this 8 million users, some are duplicate wallet? or some wallets are maybe already forgotten or abandoned.

Even though blockchain wallet try to provide better security you may not be able to login into your wallet if you forget your password. So usually importing address into blockchain wallet and saving those address's private key in safe place is advised. I mostly use only imported addresses to receive bitcoin so that i can be sure that when blockchain wallet goes down i still have private key of the bitcoin addresses where i have my bitcoins.

I don't think that blockchain wallet does have already more than 8 million users though, but even we says that blockchain has the most secured wallet (which is impossible), it always depends on the one who use that, its not on the wallet but in the device used of this users whether smartphones or PC.
The  most important is to secured the device you used to store this wallet.

blockchain.info is pretty secure..

you can enable email authorization as well as 2fa.. plus you can encrypt your wallet with a 2nd password..

so that means to use the site you need 4 log ins..

the site password, the email giving access, the 2fa key, plus the 2nd password to decrypt your wallet and send funds..

they dont seem to have access to unencrypted private keys so even if someone steals the key they will need that 2nd password..

I also think blockchain.info wallet provide better security than other similar web based bitcoin wallets. They are client based, have authorization via email system everytime when you need to login, have 2fa etc. I have never got any issue with my blockchain wallet, but i still don't use it to store heavy amount of bitcoin. Paper wallets and hardware wallets are way better than any web wallets.

How to protect your Bitcoins?

Don't use Blockchain.info wallet.

I cannot emphasise this enough. Blockchain.info wallet IS NOT by any means, safe. Just like any other web wallet, they have access to your private keys, encrypted or not. It is still possible for them to get the Bitcoins by capturing your passwords or just use a weak encryption method when encrypting the password. The 'security' features that blockchain.info wallet only protects against hackers who have your password or are trying to bruteforce your password but are not protecting your wallet against the hackers or employees who are targeting the server. A simple research would tell you how flawed the idea of blockchain.info is.

Better to have paper wallets which is also free and when you need to transfer bitcoin you can use blockchain wallet as they have address importing feature. I don't feel secure to store all bitcoin in any of the web wallets currently exist.

wow, that is impressive, I remember the time they went above 1 million I heard about it and though there is so many wallets on BC.I but now it is really handling millions of users!


first of all you should always keep coin coins in a wallet that you generate and hold offline not a web wallet.
secondly all you said are good security measures I chose a good password with 2FA and I feel it is more than enough for my needs and I can not use IP restriction because i have a dynamic IP which changes so it is not an option for me.

you assume nobody uses bitcoin and just holds on to it..

i use bitcoin. i get paid in bitcoin, buy things with bitcoin, i hardly keep any coins.. maybe 1 or 2..

so paper wallets would be a huge hassle..

Its very important to distinct this. Blockchain is technology, blockchain.info is poor online wallet and blockchain browser website.
You mean blockchain.info dear topic author.

I used to be a Blockchain.info user when I initially got into Bitcoins, but they later had several hack attempts and I had decided to move to Electrum one and for all. You can google and find this news article about a hacker named Johoes who managed to hack Blockchain.info's private keys for few accounts that generated the name 'R' value twice by using the signatures alone. He developed a script to steal about 255 BTC, but was very kind enough to return it back to blockchain.info. Also remember all your private keys although encrypted, are still accessible by staff or employees of Blockchain.info so you'd never know when there would be a day when some Bitcoins get stolen (and I assume as this happens the price of Bitcoin falls and we don't want that to happen do we?). It's better to be the only owner of your private keys by selected a desktop or mobile wallet probably SPV if you can't afford to download the whole blockchain and use Armory.

Login IP restrictions could prove to be an issue in the future, especially if we reach a point where people commonly change their IPs. Blocking TOR is a feature on some websites already, and it works well. Password stretching might be an interesting thing to apply.

A web wallet always has some vulnerability, so if you are not convinced by their available features, better switch over to different one. I believe blockchain.info has all latest security measurements including client side encryption on browser itself before transmitting to their servers.

No, tor is for different application. A hacker may hide and come under a proxy not just due to tor.

i am a late blockchain user but when it gots its second update(recently) i stopped using it even i have some btc on those btc addresses but i just stopped it i hate the new verson of blockchain so much that i immideatly switched to mycelium wallet i can not compromise my comfort with my security and in face the new version does not even let me take control on the private keys

Actually i don't too like using Blockchain because it is online wallet and i can not control the private key although there are many people who use it, and the other reason is Blockchain has interface of website and new fitures usage not user friendly especially for users of smartphone like me and i am more suitable use mycelium wallet than Blockchain.

they may recruit many experts in the field to monitor the site. and of course the site of this size is required to maintain the good name of the site. But how can you know more than 8 million people there?  :o

Thanks for the advice, I appreciate it. Yes I am talking about paper wallet when I said cold storage. For me, the main purpose of cold storage is to store bitcoins for long term (say 5 to 10 years) so yes it would work best as far as one is keeping paper wallet secure. Using an always offline PC is also a good option but the paper wallet is preferable for me as I don’t trust the durability of old devices.

Due to the enhanced development and updates Blockchain wallet runs in a much safer way even in minimal security features setup. Possibly the features provided for increased security too seems to be highly user friendly, that even a first time user too can set it up without much difficulty. Most wallets had started using two factor authorization.

This numbers are a bit crazy, one day this wallet can have problems and for sure the bitcoin price will go to the ground even if most people use to hold micro ammounts in the end it's a lot of money.

Anyway untill now it's a good web wallet with impressive numbers.

Blockchain wallet is one of the very first wallet that I use but now I already transfered my bitcoins from there to another one because I don't that it is safe to store bitcoins there because its number of users can easily attract hackers so for me it is better if I just jump into a safer wallet for me rather than storing bitcoins in a web wallet and crowded which is very prone to different attacks.

lol, you don't know anything about bitcoin price and how it changes and nothing about wallets either.

only newbies are using blockchain.info as their primary wallet to keep bitcoin in large amounts. and if anything happens those newbies will lose their coins (and it has already happened once) and newbies don't have much.

Yes Bro You are Right the Advanced Features Of Blockchain Helps Us to Protect Our Wallet and Your Funds and Also I Want to Tell You One More Way By Which You can Increase Your Security is Always Use Different Addresses For Receiving Bitcoins From Different Websites Or Services......

Yeah, no online wallet will ever be safe. Blockchain.info wallet can be useful for newbies, and maybe to store some chump change, but other than that it's pretty useless. Anyone holding relevant amounts of bitcoin inside blockchain.info is up for a harsh awakening, some day they will look at their accounts and it will be empty.

Remember to always save your BTC locally ideally in a computer not connected to the internet at all.
