Slightly killing it and slighting resurrecting it as well. Because now more people will come from the non-gamblers to become new gamblers with stablecoins in hand. Those who have been betting in the fiat scene will never shift to crypto and now these people have a chance to move from their old sites to new sites. Or the people who have never gambled before will be getting a place to settle in.
Yeah OG casinos which ran bitcoin only, they might see some changes to be done but overall it is for the good only.
It is for the good if one ignores the tight restrictions which are within the scope of for the future of stablecoins like Tether and USDCoin. That is one of the reasons why I had much faith on Dai and other seemingly descentralized stablecoins to be integrated on casinos, but sadly it seems people are more appealed by fully centralized tokens, not prioritizing descentralization.
In some way, the crypto gambling ecosystem tendency is to get more and more centralized, also depending on KYC and identification of gamblers and their addresses, it was not like that when Bitcoin was the most common coin used for gambling on the internet.
