Well anyone playing with those huge amounts should understand how much money he is putting at stake!
I think he was getting too comfortable for his own good.
He was getting lucky and lucky and just winning small shares by betting big. Obv chance would catch up with him and as we all saw, it did.
He will back with a different username, Im pretty sure.
It is also a fact that if you play huge amounts you are going to get a big return at some point.
Users usually see the returns and they do not care about the amount that someone might have lost till he get this big return. In the end, the profit that you get is less than the money that you have bet till you get it.
