This is because 2 3 Coins of the same name can also be made. Ho and no one sends you any legal notice or banner and if 10 projects come in 1 month, then 8 of them are fake, if this problem is not solved then trust in this market will not increase...
That's not a problem, everyone knows cryptocurrency is decentralized, everyone can make coins as they want, no one will be able to control it,
If you know this, as an investor you must understand how to distinguish which projects are legitimate and which are not, it is your responsibility, you have the money then you will decide every investment you make.
