All stuffs of Semux are really awesome, it's developers are professional too. If they have launched any bounties in future, I will support at all cost.
the sem really is a nice token.i want to know what is the team's plan after the signature campaign.and which exchange it will be listed?
The distribution to the BTCs and Signature Campaign is not considered a plan but a necessity to enable the idea of decentralization of SEM! There are things more important than these rewards, as shown in Q3 of that year and Q2 in 2019. However, there are good chances of some exchange listing Semux in a few weeks.
