There Are many exchanges where exchange authority listed shitcoins only for money and later, they delist these as like responsible Exchange owner. Let's Have an example With MEXC Exchange! I saw some coins Pump from 600% to 18,000%, many coins pump more than 13000% and that's make me wonder. So i also tried to buy new listing altcoins.
But i experience that, New altcoins already pump 300-500% within seconds. Lol. Although i had opportunity to buy overpriced coin cause some coins goes more than 20000%. But i did. And later team create more hype so that more people joined with then. And after a certain time, team dump their share and run away.
So should be careful such shitcoin games. It may increase your money thousands time but i think, people will loss more than gaining
Shitcoins never give good guarantee to exchange they perform very well to increase customers in the beginning but when the number of people increases then they are the main target for scamming. These shitcoins should not be trusted at all. They are never life changing and money and time should not be spent on them.
