There are at least 3 other users that have reported the same thing. All when their balance is greater than 10BTC.
It's starting to look like they are tryig to block large withdrawals so that people still play, and then put large amounts in and lose it.
It's very suprising that they'd do this now as they have recently updated their site and everything on it and sounded like they wanted to develop it further.
So how's it looking in your opinion ?
It's fair to say, your money is gone!
Usually they claim to freeze funds and then review what they were gambled on. They have previously frozen funds on two other users and then just deleting them saying it is fraud.
If you are in a country like the UK, US, Canada, Australia or another country where Bitcoin is classed as a currency, you can take them to court as terms and conditions are not legal contracts and if they claim you have had multiple accounts, they can't rob the money from you anyway. The legal fees are probably worth it for $20,000 and if you get a lawyer on something like a no-win-no-fee case basis, then you are most likely to get
some of the money back!
(usually court fees are quite small in most cases, the high court in the UK only charge £1000 for a court case and betcoin.tm will be forced to pay this if they lose)!
