Not sure about this but I think SMTs may actually be fuzzy’s idea, at least I heard him talking about making whaleshares into something similar and how he kept pushing the idea on Ned.
SMTs are on a whole 'nother level.
Whaleshares is an issued Token from BTS - which has no value and is completely redundant. SMTs in comparison are native Tokens on STEEM, with a lot of added benefits, which will enrich the STEEM-Ecosystem.
Amen to that!
