I think this is happening for most casinos that has a support with USDT. And with the rules from EU's MiCA, they have to adjust and remove the support on it.
That's why instead of USDT, they'd be using other stable coins that can be also used by their customers.
First time to see that casinos like BetFury reacted quickly in less than a week with such policies implemented by EU.
They have to obey to newest regulations from governments. USDT is only one of options for them and users, and without USDT, there are other cryptocurrencies to use on their platform and these cryptocurrencies are not banned by governments.
A discussion thread on it.
