Voted for YES.
I feel like there needs to be a bunch of caveats with this, since everyone has been looking at SMTs as the golden rainbow unicorn.
If SMTs were anywhere on the horizon, and if they were implemented correctly, and if the word got out to enough businesses and organizations that might want to use them, and they were all efficiently onboarded in a timely manner, and actually saw some success with them, then yes, SMTs might have more than a passing effect on the STEEM price.
To date, despite many opinions to the contrary about this or that affecting the price of STEEM, the fact remains that for the most part, the meter on STEEM doesn't move regardless of what happens on the platform, or in relation to the blockchain. STEEM mostly moves when the rest of the wider market does. There are a few exceptions, such as the recent week long or so pump which became a few days long dump that happened more or less without any help from the rest of cryptodom. Why that happened, who knows?
But that incident is pretty much among the few isolated events. So, to say that SMTs will move the meter in a positive way without a bunch of caveats assumes a lot, and to say that anything matters at this point if Bitcoin and the other larger coins aren't involved does not seem to be supported by the numbers.
All that said, I chose yes simply because there's always the chance, however small it might be a this point, that STEEM decouples from the market locked step, and there is also the chance that SMTs, if done incorrectly, could damage STEEM prices, too. Price can go up or down.
