Ah, but that is only true if you aren't speculating on getting more. If you can get more, then you will rationally risk getting less.

An example of a lottocoin was given on Reddit by one of the developers. Everyone can move to the side chain, but only one person (chosen randomly) gets to move all of the bitcoins back. Everyone else gets nothing.

How is it possibly not clear this creates even more opportunities for speculative markets?
