If real crypto is available from FunFury wheel for rank 2 and above, why then rank 1 has real crypto on the wheel? Why not replace them then something different from 5k/8k/10k FunFury prizes?
Here is my another experience with FunFury tokens:

This morning I've got 10k tokens from the wheel and played Dice with 100 bet and "fast" option switched on and 50/50 chance to win. Took me 1 hour to lose all tokens, but easily got 145 place. I am sure that if I work on the tactics (for example bet minimum, wait for series of looses, and then increase bet and wait for a win) I would improve my position.
I would guess that if you kept it at a lower chance to lose, and kept on winning as much as possible with the same amount then it would have taken you longer to lose it all and that way you could have made a bigger wagering number and a profit number at the same time.
