I understand the smallest denomination, 0.00000001 (did I get the right number of zeros?) is called a satoshi, after the creator of Bitcoin. Correct me if I'm wrong here, with 21 millions coins and 8 decimal places, you have about 2 quadrillion [1] satoshis, which does seems to be quite a bit to last for a while. I'm guessing we hit the 2038 problem [2] first. Of note, the US money supply, even including 2 decimal places, creates a space of 331 trillion units [3], as of 2016 [4].
