Sem had been popular in bitcointalk as I see, but I think they are some question need to solve.
1.the exchange need a bigger platform.
2. the spread need more coin,I think it should invite the community member who was ability to do the market.
as we know that EOS had a lots of market manager to join, the mining node should be control to the guys who was popular in their native community.
3. PK with other project,I think SEM need a office team member to represent，when the guys was familiar to the players,it would be more successful for the project.

this is my advise for this project,I hope the dev can adopt it
