That's a big money on today's current price, I regret that if I'm on the situation of niagwai and it will be better for me if I'm not going to share my losses. That will make me feel bad all the time and I can't recover immediately with as the price of bitcoin is still pumping.
There is no doubt in this fact that at present where it is hard to earn one bitcoin, losing 50 is a big trauma and torture as well. You are never ever going to come out of regret for playing with such a big amount and I believe this person must be a gambling addict, otherwise no sensible man is going to bet 50 bitcoin ever because he knows the worth of bitcoin and is well aware of the consequences of losing such a big amount.
