Initially registered with a other account, but now it is more convenient to use dollars or USDT. Is there a casino where you can switch between currencies without creating a new account?

Yes, there is such a thing — on Pin Up casino app you can choose the account currency when replenishing. My main account is in Euro, but I easily replenish in USDT — the system converts everything. You don’t need to create a new account, just choose the desired payment method. They have a multi-currency system, and this is convenient, especially if you use crypto or cards in different currencies. Withdrawal is also possible in the selected currency.
