This is an unregulated market, there's nothing we can do about it. And instead of looking for solutions to this "issue", we should let the market decide whether those shitcoins/tokens survive or not...but I'm pretty sure that more than 95% of those new coins/tokens showing up everyday will most likely dissapear in the long run.
As we can see, there are lots of coins that are being offered in the market every single day. Does every single coins that are in the market really usable in our daily lives?
Let's be honest, most of the people in this market are not looking for a coin/token with a real world use case, no one cares about that anymore, people are more interested in making money with cryptocurrencies.
