Lets wait for a listing on Probit to check the development and the price of WMA. Sometimes it is better to buy tokens after listing.
Usually bounty hunters start to sell tokens after the listing. Does Weemat.io have a bounty?
If the project is not interesting, then they sell tokens. And if the project is successful, then usually hold.
It is possible to find out that the project is interesting only after some time after IEO. Investors will not sell tokens soon after iEO.
