Honestly, it's not about high roller or small amounts, but rather its more about the possible bid ranges.

0.5 to 1, is only a difference of half a BitCoin

5 to 10 is a difference of 5 BitCoins.

what I mean to say is that with these types of games/pyramids, people bid if they believe there is a good chance of making something back (sometimes).

With bids like 5 - 10, once people start bidding 10, no one will bid anything lower than, because it slows down the whole chain overall, and then what would be point of even having anything other than 10 as a bid value?


Games like BidCoin work for larger bid ranges because you aren't waiting in a line.  BidCoin has a random number generator.  Even wins, odd loses, and a roll of 500 wins the jackpot.  You're not exactly waiting for anyone else.

but in the end it's all still a gamble.
