I use coinpoker(CHP) to play texas holdem. I think it isn't a huge problem if u spend little amount of money.
I decided to spend little for following reasons...
- wanted to see how erc token based wallet works such as myetherwallet & metamesk
- I was very bored from trading crypto... it's been so slow compared to last month xD
once again... using little amount of crypto should not be a problem as long as you keep it just for fun and not serious
