I'd say it's more like a ponzi because the market volume is so far from accurate due to the chameleon hoardsters. They will dumptruck eventually, so anything gleaned from looking at current market stats is really just a facade. Wait till the whales start selling...And no disrespect to Satoshi who is most likely Finney but if he or his children ever decide to dump their share that most appraisers tend to consider "missing for good," you can bet the price will take a monstrous hit. Thats why I consider BTC a ponzi. The current dynamics are an ill reflection of the actual level of buyers and sellers. And there is no real way to assess number of hoarders due to not knowing how many BTC are lost or simply forgot about.
