Been hearing betcoin.tm scams recently.Though not only in this forum but on other betting sites chat boxes.This quite sad and lame that you need to sign a message to request your own withdrawal.Whatever the reasons maybe but this is not the correct way to handle it.As ndhnc said ,they are not processing the payments on the old addresses .I'm sure they can do better than signing messages to handle the old users.Maybe ask them to submit a support ticket with recent address.
I have not heard that they scam anyone recently, where you heard it? I have made several withdrawals from this site without any problems, but yeah they requires a sign message to withdraw. IMO, this is good for players because their balance is safer. i.e when an account is hacked, means that it is impossible for the hacker to withdraw the funds to his wallet unless the hacker also hack user's wallet.
