Question is: how can these people make money? initially, there will be some people mine the coins, and they will dump all once the exchange exist. If dev artificially pump the price, will any people really follow him and buy?? I won't imagine there are people so stupid and let dev with huge premine to dump. So I think dev's pump is useless as those who mined the coin will dump regardless. But why I still see many pump then followed by dump in these shitcoins??
If there is a so called fake price pump and if people will follow it? Yes in most of the cases they will follow it. Why? There are now eyeing for the profit purposes that will create after that bull run. All in all, they are playing with the devs action to make money. Most of the traders already know that shitcoins come and go so while it's on the run take the ride to grab some profits.
With this kind of activity that happening in every altcoins in most of the cases, no way it can surpass the status of bitcoin today so it's just an mere fact that alts are made just for profit taking.
