They can create more bitcoin if they change the standard, but that's unlikely anytime soon. Not all cryptocurrencies have a forced count limitation, so they can be inflated just as easily as fiat currencies. Most of the proposed central bank currencies have no real limitations... for obvious reasons.
Technically, a cryptocurrency isn't a ponzi scheme. It's just creating "money" out of thin air and hoping people will use it, like it, and then perceive it to have value. In the end, it's just a number on a register. The Chuck-e-cheesy tokens might actually have more value as they're made out of metals... or at least they were in my day... might be plastics now.
If there's a serious security flaw found, a cryptocurrency could be cracked and it could be worthless in an hour or less. That's my biggest fear with them. I also don't like the lack of privacy on the block chain... or at least most block chains.
