Ratings and reviews

The only way I buy and sell Bitcoin these days. You can cash out with zero fees via the lightning network which was a game changer for me I don't know of any other exchange that does that. I also love how you can buy Bitcoin with cash it's a lot more private and ensures that transactions are final. They also have the best customer support and will actually answer emails and dms

Probably one of the hidden gems of crypto. Its changed the way I manage my crypto as well since I can buy with the privacy of cash and sell with zero fees. I needed help to get started and their team was super attentive and helpful.

super cheap transactions + transactions take 15 mins or less 😁- UNBEATABLE .....!!!!!!!
