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.
Yes its a big regrettion who owned that 50 bitcoins because if you exchange that it will makes you millionaire now. Its hard to recover if you lose that big amount of bitcoin because it is still in your mind and it is hard for you to forget that big amount of bitcoin. So i think just give up gambling.
