I have been a Wolf user for 4 years and when I can afford to make a deposit I do it and play there, regarding the chat I have to say that I remember that Wolf gave rains in different cryptocurrencies and they also gave higher amounts, for some reason they removed the rains good ones they had and they started to give rain only at USD 0.01 each and this remains the case to this day, another incentive they removed was a reward that you could get just for visiting the casino daily.
it's wild that you are complaining about not getting enough free money.
besides their rewards program, which is already very competitive, they do free twitter giveaways almost every other day, plus regular chat games run by mods every hour or so.
if i remember right, they had to remove the 7day streak reward, free faucet, and lower the chat rain amount because those were being heavily abused by farmers with hundreds of accounts.
