I'm thinking that he has plan to commit suicide now. Because of his crazy betting that will end up his addiction unless he is one of the most rich guy that holds thousands of bitcoin. If he is one of it, then that 216 BTC is just nothing to him and thinks that he has donated that to nitrogensports.eu but still that lose is regretting most of us.
Even thought he losing that huge amount, i'm not sure if he did that just only for stop his addiction in gambling. We don't know about his bet previously in gambling, maybe he already won more than 216
BTC or maybe that's just "normal" bet for him.
Yes maybe that's just a normal bet for him either that he just won that amount from his previous games. But still, that's really a wrong move that you will play YOLO with that big amount. 1-5 bitcoin is quite acceptable if you will do that but with hundreds of bitcoin. Well that is a different, you can do a lot of things with that amount, still we don't have idea for his intention.
