Ok you think bitcoin is not a pyramid scheme, that's fine. But are you denying the block reward for bitcoin cuts in half over time to eventually reach a low of 0?
That is exactly what Bitcoin does, and has done since the very first day it was released more than 3 years ago. There have been absolutely zero changes to the block reward. It is that trust that has been built over time that makes Bitcoin successful.
Answer this: How many times has SolidCoin changed the reward scheme?
Pyramid scheme, bait-and-switch, pump-and-dump, I not sure which scam term is most accurate of SolidCoin, but make no mistake, SolidCoin is very much a scam designed to benefit early adapters at the expense of later adopters.
