Currently coinmarketcap lists the total supply at 341,736,004 STEEM. I believe that takes into account vested STEEM, which I think is important for macroeconomic analysis. So at a price of $0.02 per STEEM, the market cap would be $6,834,720. That is pretty low. For $68,347 you could purchase 1% of the token's supply...

I'm interested in why the STEEM price has been going down so much despite innovation in the ecosystem. I am guessing there are some large sellers who keep depressing the price. Also probably much of the rewards go to low-value participants who just care about cashing out pennies ASAP. But I'd expect significant buy pressure at these low prices, should the technology and blockchain continue to operate without major flaws.
