I don´t know zzan and jahm projects, but my thought on these new projects and the amount of new tokens that are being released is very positive, because now you can get rewarded with more than one token at a time besides STEEM and SBD, which creates added value for the community.
Although I like what is being done and the path we are taking, this can delay mass adoption, because now we need to think of new ways to present all these projects with a favorable and not confusing view for the average person.
