How many BTC he has and how he collected them
He had thousands something like 250000 its unknown now since hes burned many in supporting BCH and he got them by being a very early adopter when the reward was 50BTC and you could earn that in a day just by mining
I do hope he did burn them on BCH, but he probably got a lot of them back selling from the top. He's a criminal charlatan, but he's no idiot.
