#2 Is Steem being swapped easily with other currencies.
Yeah - that's the most important factor. When you can exchange STEEM directly for fiat, like you can with BTC, that's when you'll see the break/divergence in price from BTC. At that point, my analysis will primarily be about STEEM-U.S. Dollar.
Then it's about exposure and growth.. someone will come along and offer whats needed. Until then.. it's not volume enough. It will get there though. It might be the result of advertisers getting in; which will change the landscape. I envision this as an early UBER .. but once the guv got involved.. UBER started to suck ;)
