Market cap
Price multiplied by circulating supply — the market's valuation of every circulating unit at the latest price.
Market cap is a projection, not money invested and not money that could be withdrawn. The last trade's price is applied to units that were never traded, so a thin market can carry a large cap. Coinmico computes it from its own price index and the best supply figure it can verify, and shows volume alongside it so the two can be compared.
