People should do their own research and not blindly invest in anything they see. The moment people stop pumping money in shitcoins there will be no incentive for the projects behind them to pay $100-$500k for the listing.
Coins are mostly removed because of their low volumes, but low volume is an indication of there not being much interest in it, and in most cases the networks themselves for that reason are vulnerable to double spend attacks.
We cant do anything with these delistings since the decision would be always on their end.Its just normal for them to remove out which arent
already beneficial for them and free up some space for another coin to come in.Rinse and repeat= Generating income for them.
