Monero
Top 10
Monero can be used.
There is "localmonero" and soon also an integration as basic currency in BISQ to change Fiat directly into Monero (and vice versa).

Since BISQ is open source, it shouldn't be too difficult to modify the code in a way that it can be used within the bite ball wallet.

The gamblers who buy/sell bite ball via centralized exchanges certainly don't contribute to a meaningful distribution.
