Jack is a great Bitcoiner. Speaks really well. Represents the community well. Was a big part of EL Salvador early on with Bitcoin Beach. 
You’re right about Strike though. I used it a few years ago to buy a good amount BTC. Spreads were great and it just worked well for me. A lot has changed though and I don’t use it anymore.  Seems a bit captured now & harder to work with. 

 Me rappelle pour le Salvador et les pays cités en Asie pour l'Afrique j'avais observé sa démo lors de Africa Bitcoin à Accra l'an dernier en cette même période.. 👍
