Without any evidence, I am not sure we can trust his story at all. He claims to be some kind of high roller and brags about his deposits and withdrawals from numerous casinos.
A month ago he claimed to have deposited 100 mBTC at a 1xbit casino. 100 mBTC is nowhere near $ 5k.
Ruximix is still in the same place as Ruximix is still saying that s/he has deposited 5000$ and took out 15000$. So, the previous time Ruximix told the deposit amount and present time told the deposited amount is same. But yes, it is something seems to me not perfect as it is something which seems on behalf of 1xbit.
