How much free credits does one get and how much do additional credits cost? Kinda sounds like a bait and hook scheme but maybe not. Afterall, some people like to gamble.

you cannot buy or sell credits. This is just some "worthless" in-game currency. You get free credits for signup and you have to bet with them. If you bet well you get more credits, if you bet not so well, you lose credits. This will help determine on who is the best predictor.
You cannot add credits artificially, e.g. with buying, as this would distort the betting towards "who spends most". It is a fair and free game in each round, but with REAL bitcoin prizes
