I have withdrawed 3 times without problem btw, and I do 30k multiplier rolls per day to get bonus tokens, (1 token bet, on win set to high, reset to starting stake, on lose set to low, reset to starting stake).

I can lose up to 600-700 tokens but you get 1300 tokens from the 2 challenges (multiplayer rolls per day and multiplayer tokens betted).

I am at 118k tokens atm after 40 days (I converted 20k satochis as well)
