DarrkPhoenix: Actually bitcoin does somewhat resemble a pyramid scheme. This is because 1) there's a hard limit on the maximum number of bitcoins there can be and 2) the value of a bitcoin is basically the amount of economic activity bitcoin is being used to process (the size of the bitcoin economy) divided by the number of bitcoins. The more people using bitcoin the larger the bitcoin economy, and hence the more each bitcoin is worth (due to the limit on how many there are). The people who see bitcoin as an investment need more people to start using bitcoin to pump more actual money into the system and drive up the value of bitcoins. However, if people stop buying in then the value stagnates or drops, and if people start trying to cash out then the whole thing starts to collapse. Ultimately this can look like either a speculation bubble or a pyramide scheme, depending on how much credit you want to give the people who got in at the very beginning.
To me it looks like speculation bubble. The idea is not bad though, might be other form of cryptocoin or similar might stick around for longer time. Maybe.
As for the maximum number of BTC, a there is apparently hardcap, but if ive understood it right - its going to take quite awhile to be actually a problem. Also i think it could be change as well. Anyways, its more likely BTC is going to run into far bigger problems than that.
Oh i think BTC are also disappearing all the time as people simple misplace them or whatever.
