When he losses 5 btc.he should have realize that luck wasnt on him.and stopped right away.why waited for 50btc .its a big loss that can change life for good.if he only valued the BtC as fiat
So true, that's one of the problem with gamblers when the greediness strikes you wouldn't care about how much you will lose. I still can't believe he just wasted that huge amount of bitcoin, we should have self control and discipline in gambling because it tends to be very addicting.
When someone already lost a relatively huge amount of money, self control will be hard to maintain. Lose control because of the need to chase his previous lost will take over his mind and mostly will lead to another dissaster. It is better not to play with 'fire'. Never play with the money that can ruin our mind if lost it.
