Technically, there's a finite number of Bitcoin... Until someone figures out how to make counterfeits. Sure there are plenty of clones and Bitcoin-like, but fools gold is not gold, zirconia is no diamond, and a counterfeit Degas is no Degas.
Yeh but the $ value of a bitcoin is more about the % of bitcoin you own rather than the actual price, so in theory you could divide bitcoin into a million smaller bitcoins and you should have same $value for % but the price for one would now be a millionth ( but of course you would own a million , so in a sense the quanity of bitcoin is like any commodity in the sense you could buy tiny tiny amounts almost infinitely small amounts, which means the actual figure size of bitcoin is sort of arbitrary, it's the percentage of the whole of bitcoin you own that matters, though there maybe some psychological affects .
