If you're serious as fuck about your bitcoins, consider a hardware wallet like trezor. Paper wallets can always be lost or drenched in water (yup, happened to me before). Hardware wallets are pretty strong and have lasted me a year or two. I plan to buy two hardware wallets soon in fact

WTF, drop it in water?

How about making multiple copies of it, perhaps writing it down on a laminated paper with a market to be water proof.

If you keep it on a small note paper somewhere in the house then of course it gets messed up.

I agree when you make the paper wallet you should not make 1 print only of it. It would be crazy if you did to have it in a area with water around it. When you store safely you would be smart to have at least a copy always stored away.

I do like hardware wallets more and more. Also 2nd factor devices. I see these becoming more and more popular in future. Which is likely a very good thing.

I keep seeing all these posts that someone can hack my wallet. First I did not think that this could be done? If it can be done, how can I prevent it from happening? Does my wallet need to be online in order for them to be able to hack it or can they still hack a paper wallet?

I've recently downloaded The Electrum wallet.
And u have the option there to make a double authenticator wallet.
So you always have to double authenticate with your phone.
So if someone wants to steal your Bitcoins, he will need your private key and your phone.
That way someone on the other side of the world cant hack ur wallet.

yes a paper wallet could be hacked : the attacker just need the private key, and could obtain it if you dont print it securely.. , of if you generate it online .. you see ?

as far as I know hacking wallet can be done if someone know your email and passwd,then asking password recovery on the online wallet site,this one can be prevented by activating 2 factor authentication and sms message notification

Well its not that easy to know the password of wallet, email and then SMS.
I little carefulness is setting up all these can save our accounts from being hacked.

There are also situations where you use a wallet on an exchange that gets hacked so you are relying on their security that was flawed.

We cant say that the online wallet which was hacked, its security would be still the same. It maybe possible that they have upgraded their system and now there is no loop hole in the system. Secondly we cant only blame the online wallet security for it. What if we don't keep password difficult and secure, as it should be.

store them only for trading and small amount and activate auto withdrawal on your cold storage

Quote from: btcltccoins on February 23, 2016, 11:49:44 AM

Yes storing in cold wallet is the most secure way. The only disadvantage of using cold wallet is that if you have to do lots of transactions then it takes a lot of time. Otherwise cold wallets are best for savings.

another disadvantage is to remember thta the key pool contain only 100 key so if ou keep create new key to receive new funds on your cold storage and forget to do a backup after 100 key your next transaction will be lost when you want to use that back up again

Those hacking method are mostly brute force. You usually encrypt your wallet with a password. If your password is short (less than 8 characters ) it could be cracked by brute force methods. It needs a while, and the hacker needs a computer with lot of power, but it is possible. Especially, if the hackers knows the length and some chars of the password.
To get sure, choose a password of at least 12 characters including letters, numbers and special characters.

then don't forget to activate two factors authenticator, and use email or phone confirm to open your online wallet. it will be safer.

Always secure in offline your private keys or backups.

Never trust any other website which hold your BTC 100%, cuase we seen to many times exchanges and many other services going down with all the investor money.

And to reply to your question an hacker could stole your wallet really easy, so at least protect with a good password, so that it will be nearly impossible to break if it is enough resistant.

I think offline is the best to hold bitcoin. Yeah it is true don't trust any website which hold your bitcoins also the online web wallet there's a possibility that the site will be down and they will announce that their website is hacked..
So offline wallet is still the best to hold bitcoins. and secured it. So that you are in far from hackers..

Spliting coins in different online wallet is a good idea. Also i recommend to use a strong password.
and never share your password with anyone. Most of the time Hacking is done because of our lack of responsibility.
Follow the best principles of Passwords and your wallet will be safe.

Hacking is very hard to prevent once they target and focus on yours. The best thing you can do is to split your bitcoin into different addresses you have.

That's right, if you are targeted by a hacker then you can't really save yourself forever, he will not leave you if he see much coins in your wallet, better to split them in different wallets and different places, keep some in cold wallets and some in online wallets. You will feel safer that way.

To be fully safe from a hacker get a paper wallet and put all of your funds onto it, That way a hacker will have zero chance of stealing your coins unless he breaks into your house and knows exactly where to look.

Well i myself never used a paper wallet and i even have no idea about it actually works or how to use one, but it is also safe to split your coins in different wallets because if one get hacked then your other coins will be safe, and try to split them in small parts as you could lose much if any of them get hacked in case.

yes it was one of the best ways, do not save all bitcoin on one wallet and also do not forget to always use double security.

Be careful with exchanges. You never know who to trust. If you use one, don't put much on it. I lost some bitcoins in Cryptsy.
