Do I need to pay tax on Revolut crypto?

I'm a bit confused about taxes and cryptocurrencies. I use Revolut to buy and sell crypto, and I'm wondering if I need to pay tax on any of the profits I make. I've heard different things from different people, so I'm hoping you can give me a clear answer. Is there a specific tax rate for crypto transactions on Revolut? Or does it depend on the type of crypto I'm dealing with? And how do I actually report and pay these taxes? Any information you can provide would be much appreciated. Thank you!
