I am not a Bitcoin user and I also don't get it. Could anyone else please explain what this hash on the piece of paper is? Is this an address used to send Bitcoins to?
Using a Bitcoin address provided by a web site to store your coins is Extremely Unwise. You would be giving the owners of that site the power to steal your money later.
