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.
