Volume couldnt be done at current time. We have so many different casino platforms available we cant at this time add a volume bonus that could be used across all...in the future if and when we can we may add volume as a secondary choice for all players.
A btc bonus right into the account which can be used across all platforms is alot easier with alot less headaches. Plus, the fact you get bonused even when you win is a nice way to thank players as well.
Keep in mind to prevent what you mentioned about stopping play there is a minimum of 5 bets per week.
