I'm relatively new to the world of online gambling, a little under a year. I've lost over 180BTC , it makes me a little sick to think about.
I posted some of my wins here
www.mobtcs.com , I've had some decent wins, but I don't hold onto them for very long.
180BTC must be a very big money, everyone here is dreaming for that. Your situation is most common in gambling or in trading. People make some profits but loose more than that in next round of gambling or trading.
