It is not even about fixing something, it wasn't their fault to begin with that gamblers had to pay a high fee because it was something about the network and wolf.bet team had nothing to do with it. However, the great thing about this team is that not the fix itself but the "care for the community" part. They didn't had to do something like this, but they did it anyway and that shows the people that they actually care about the community.
I have to disagree with you here. The BTC network fees were never as high as $8 - $10 while ETH gas fees were closer to those values which is why Wolf.bet is definitely at fault for not resolving this issue quickly. Sites like Bitcasino charge zero withdrawal fees in comparison.
However, they did resolve it even though they took their sweet time which is all that matters at the end of the day.
