Yes, everything is simple. From the new coins does not make sense. They are created just like that. The maximum benefit from them only to traders for a short time and no more.
That sounds more like a pump and dump scheme.
This is partially true for many coins out there which were pumped and then the owners dumped it while in the bull trend. In the end you are parting with your precious fiat and bitcoin to buy those shitcoins which have no long term value in growth. Unless you are a bagholding advisor of a certain project, I dont see any reason why any trader would continue to hold a shitcoin during a bull run but rather sell it for the profit and get out.
That is what many investors are afraid of when they participate in the ICO, many tokens after entering the exchange will certainly occur such a scheme and there is often price manipulation created by the founder of the token at the exchange, hopefully there is no shitcoin anymore and more respect investors who have participated.
