It's a huge percentage if it's really true. Since stablecoins was introduced and been adopted by gambling platforms, I stopped using bitcoin on my gambling activities. Seeing my bets in form of decimal satoshis is very confusing to me as well as calculating the profit and loss I get.

This just means bitcoin will always be the top choice by people who use crypto. Even if it's possible to gamble with other cryptocurrencies like xrp or doge which has cheaper fees, gamblers will still prefer to gamble using bitcoin.
