An SMT will be traded through STEEM, so we won't have a bunch of SMTs and STEEM just one of them. We will have STEEM, and then a bunch of SMTs on top of STEEM. Market-wise, this will most likely boost demand for STEEM, as a token.
Also, the SMT generation mechanism is way more complex than just a token issuance on the Ethereum platform. When you launch an SMT, you literally launch a thin layer of Steem-application-processes on top of your content, including your own rewards pool, your own inflation model, your own voting and curation algorithms and your own vesting mechanism.
Hope this helps.
Thanks for your detailed explaination. What you meant is that people must buy STEEM first before using SMTs? I understood STEEM somehow will be in the middle of SMTs but did not know the exact relationship.
Yes, the SMT generation mechanism sounds very complex. I hope the steem team provides an easy way for us to use it so SMTs can be used by the majority of people.
