^ Please dont mentioned GP here, that account considered as a lost long time ago. It is quite good to see a gambling forum without that name.
Back to OP, until now you did not get any response from the Bitcasino? But don't worry if this is will not be paid I don't know what will happen to the account of Bicasino here, probably they have flooded red feedback, I hope they will not.
Nevertheless, your won is too insane, kinda you are very lucky, and can please share if you have a strategy used?
