I've played with the gambling capital of 0.15 BTC . all gone in one day. I wondered why I did not stop when the money I left 50% of the total. but I knew it was a risk in gambling. I still like gambling regardless of the outcome it

.As long as you having fun and I certainly hope you can afford to gamble that that. 0.15 btc is a fair amount, losing that in a day is a large amount though I feel. Maybe you made it back ? Hopefully better days are ahead of you and you will recover your loss. Just keep your head about you and be careful.
