What I can say and suggest for you is start over all again, with assumption that bankroll did not go anywhere and did not get rekted from trades or gambling as accused you have much more than enough to start everything new, the bank roll is big enough together with knowledge and asset (website codes, operating model) you can easily come up a whole new thing/ new webite and brand (with different identity of course) together with buch of attractive contests it's a sure and far better chance of success rather than keeping betking.io since it's dead already and let it be. So many dice sites are popping up and that's the chance as well as advantage for you since they will and certainly do not have that much bankroll compared to you (again, assume the coins are still there).

It might be not good for me to say so, since it is a kind of giving hand to cheater in people view, but that's the fact. Kill the dead brand and go for a whole new thing is better lol.
