It is a well known issue that they have the slowest withdrawal process, maybe atm they do not have that amount (9.84btc) then they asked you to make 49 x 200mbtc withdrawals. Indeed, it does not make senses why they should ask this type of withdrawal.
Keep updating your issue here and in the scam accusation thread, hope you'll get your money. Anyway why you decided to deposit and play in this site while there are some issues like their rigged slot games and slow withdrawal?
