I think you made a bad choice, honestly I haven't made such bet. But, the way you're telling it, it seems that you can afford the btc that you've lost. I really think that the more you gamble the greedier you get. You should've secured some of your winnings. I haven't lost big amount of money before because I just limit my self when gambling.
It's absolutely preposterous to gamble and loose that much bitcoins in this time and age where just Because10 bitcoins is more than my annual income. I think loosing this huge depends on the individual gambler's attitude.
Maybe for you or even for me it's already a big amount and honestly I am not that kind of a risk taker although I would say I have that amount of money right now.
