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.
