Altcoins are suffering today because developers are not putting much effort, do you remember the effort they usually put when they first started, I mean when they were raising fund? You could see them dong lots of promotion, hiring hunters to showcase them to the word and many more, but how many of them still do that till date, the moment they enter the market, they expect the market to just continue to create awareness of them to the public automatically? No.
Imagine that I have a beach, and after constructing it, I dont ,market it, how would people know that I am existing, it is until the point where I am fully established that I leave the work to referral, but how many referral do refer them to new people? Altcoins projects needs to do more campaign, that is it and they will bounce back.
