It seemed to me like some kind of pump group

There is also a pump group that is set up for good purpose. The end always be badly.
I think this thread was useless because most of the shitcoins are died slowly. But those are expecting more profit in token investment they will loose the investment at anytime. So few peoples only involved in these kind of activities.
Shitcoins already in the market are gradually zeroing but he sad thing about it is that new ones are coming up now, the new ways of scamming now in ICO is also to come up with a shitcoins, they will surely create a system, distribute your token and leave it to the system to automatically kill it and people will eventually forget about it.
I really dont know the way these shitcoins can leave the market completely because if you are looking at whitepaper, their white paper is also promising and convincing enough. I mean most coins get into the category of shitcoins due to improper managements and due to lack of promotions but theoretically all the coins are same in the beginning days.
