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
That is the real fact which is, that a coin is listed in an exchange doesn't guarantee the coin has a good potential it could be possible that they pay the exchange just to succeed In their dubious act, the reason why most time it is important to participate in the early part adoption of a new coin such that before they could think of scamming you must have gotten a little profits that is if you have not been overly greedy of waiting too long in the market.
