It is a possibility. I also learned that many gamblers are using stablecoins instead of altcoin or Bitcoin in their gambling habits. We cannot blame them because the deposit and withdrawal fees are lower when they use them.
I think the real problem comes from the availability on how to purchase cryptocurrencies. If it's easy to buy Bitcoin and the transaction fees are cheap, I think it will be used more than stablecoins or even fiat. Traces are low and they can get away from their wives' questions.
