I understand but, it does feel good to finally see him pay for his actions. I lost a good chunk of money with his endorsed projects first with SETHER, and then with another project don't even remember the name lol.
I think the second could be GHOST or you mean ESH. He dumped his hodling and made the coin crash and people who bought because of him lost hugely. But ghost is coming back, around $0.40.
Anyway, I think that his arrest won't be good for his person and not that it will affect cryptocurrency at large.
I think it's mostly likely for not paying the US government rather than endorsing any scams. Spain's judiciary has been extra favorable for financially accused billionaires for quite a time. But the real deal would be how largely the US goes after the extradition and how useful the spanish court would they find the money stack of McAfee. Though McAfee is a controversial person, he's one of the well know person in tech world who is all into crypto.
