I don't know much about crypto, but sometimes I have to deal with it - I pay for freelance services once a month. Once I needed to urgently buy bitcoin, and my usual exchange froze. I came across https://paybis.com/buy-cardano/ - at first I was afraid that I would get confused, but everything turned out to be quite simple. I was glad that it was low fees and I didn't have to sit for hours with documents. In the end, I did it in 15 minutes. Now I keep a link to them in reserve - just in case.
