Team of Weemat.io started listing on exchange and it is good for development of token economy and ecosystem of the project. I think that such things like bounty and airdrop also will be useful. Besides for development of ecosystem Weemat.io has a referal program.
It is very good that Weemat.io has listing on the exchange with a big liquidity but it is very important to developm token economy to create demand in the token.
Of course, if the project has its own coin, it should be traded on exchanges. But all the same, the value will be given to the coin by how the project will develop and how successfully it can attract new users!
