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.
So basically you are complaining about "free stuff"?
Almost every casino gives more in the beginning, but as time goes by the prizes are less and less... it's kind of a normal thing. If you are a more serious player, over time you can reach a higher rank that offers more rewards, but not all casinos have that either. Some casinos are simply what they are and offer what they offer, there is no room for complaints... maybe some positive criticism can affect them, but there is no need for that either. You play where you feel good and where you think you can do better.
