USDT casinos
The best USDT (and other currency) slots can be played directly on trustworthy Tether-friendly websites first. In essence, you can bet with USDT at these casinos. Some people combine fiat and cryptocurrencies, even though the second largest category—casinos—also accepts deposits in ETH and other cryptocurrencies but requires you to convert your account credit to a certain fiat currency first.
