If say 4 BTC worth were contributed, the odds of winning the price of .8 BTC are 1 in 40. I see those are pretty good odds of turning .1 into .8! And more importantly if it reaches 8 BTC, the odds of winning 2 BTC would be 1 in 80.
Regarding donating directly, I'd like to keep some privacy for her. We are holding a local fundraiser at a bowling alley, but that's much different than posting personal info on the internet.
No, that's very shitty odds. You can go to any dice game and bet .1BTC @ 11% odds to win .8BTC. You are offering the same payout but at 2.5% odds. That's horrible.
Asking for donations for a private cause is extremely shady. If it was a legitimate cause, you would have no problem giving information as to where the money is going.
+2 to this point
