When I try to take Jack seriously, and say without profit driven decision in the background, as for his involvement with bitcoin, I'm coming to conclusion that all the time he spent on twitter in the last decade or two was a real torture for him.
On the other hand he was well of, he could have left at any time he wanted to, but didn't. So he is contradicting him self in his actions, and obviously there is a lie somewhere in between.
Yes, I’m not sure what to think about jack. My guess is that he might be sincere but just lacks genuine backbone and conviction.
We can say people change and improve :)
