Sorry, but I can't answer to your question. The information about amount of bitcoins on our hot wallet is confidential.
How much BTC do you have stored in cold wallets? Are you willing to prove your solvency (though it can't really be proved since you don't have a max win).
Anyone have a deposit/withdraw transaction from Betbit.co? I'd like to try to do some blockchain analysis and see if I can find how much they have in their hot wallet.
