I was juts reading Forbes news and I found this news about a guy called Virgil Griffith, who was arrested for teaching about cryptocurrency.
Man! I thought The US had accepted crypto in 2018 at least that is what i was told, then what is this?
According to the aritxcle maybe The US has not fully accepted crypto juts like China. you can read more at https://www.forbes.com/sites/jasonbrett/2019/11/29/us-authorities-arrest-virgil-griffith-for-teaching-cryptocurrency-and-blockchain/#db602d042cba
UPDATE;
The man was arrested for teaching crypto in north Korea, But he was arrested by the US authorities, brings another question, why would they arrest him, I mean he had no permit to travel there and do all that but still.
