Oh, well my main idea was just email gambling games. The other stuff is all just variations that will maybe work with different models, whatever.
I meant people buy a scratch card for like 0.1 - 0.4 BTC then if they win they get BTC's back
Yeah, me too. Maybe I should go review what I wrote
The "card wins for sure" was just a possible option to give if you wanted to guarantee to brighten someone's day.
Yeh we could do this but we'd have to work it all out, as the fact is that we'd need to make profit and have a wallet with starting BTC's
I would say to offer the top prize of 10 BTC and every 0.5% get it then 9BTC's = 1% etc...
