I think I've developed a strategy on a certain gambling site, because I seem to be performing quite well.
Here's how this will work:
1) You send any about of BTC from 0.005 to 0.5 to the gambling deposit address.
2) I Skype you, fully clothed, and begin to gamble.
3) If the balance of the account reaches 110% of the initial deposit (ie. 10% profit), I will pay you 105% and keep 5% for myself.
4) If the balance of the account reaches 95%, I will take off one item of clothing of your choosing. With each 5% reduction, I will take off one piece of clothing.
5) I normally wear 4, so if we hit 80%, then with the next 10% drop, watch me get spanked. Another 10% drop and I masturbate/give a blowjob/handjob, basically whatever you want.
It's a win-win - you either make 5% profit, or you get to see a great show!
I also don't intend to let the account balance hit even 90%, so don't add me hoping to see me naked.

down estimates (the users earned more than what is written). Also, past performance does not indicate anything about what future deposits will gain.

I am developing a similar strategy. So far, my investors haven't been as happy with hearing I will get naked once I lose their money.
