Can I buy USDT in the UK?

I'm a UK resident and I'm interested in investing in cryptocurrencies. I've heard about USDT, which is a stablecoin pegged to the US dollar, and I'm wondering if I can buy it in the UK. Do I need any special licenses or permissions to do so? Are there any legal restrictions or regulations I should be aware of? Can you recommend any reliable exchanges or platforms where I can buy USDT in the UK? And finally, are there any taxes or fees I need to consider when buying and selling USDT in the UK?
