Hello there fellow bitcoin gamblers. I have never posted a thread before so I will just be straightforward with my question. Betcoin.tm is a bitcoin casino which I have won a bit of money on. The problem is, I can't figure out how to withdraw my bitcoins. When I go to my account, and press on the button " Add Withdraw Address", it gives me a list of info I would like to update i.e. my bitcoin withdrawal address. So in order to prove it's my address, I need to sign a message. This is the part that stumps me. I use Multibit as my wallet, and I will sign the content they give me to use as a message. Then I paste the signature into the box specified. But what happens every time, is an error pops up saying "missing address". If someone could help me it would be much appreciated.
