That is the risk of being decentralized since everyone else can pretty much deploy their own coin, but hey, there are also few hundred thousands stock out there or even million, some of them are simply money grab and scam without a promising future so it's basically the same.
It's just the investor that need to be a "little" smarter so that they don't get their money invested to crappy coin and choose better one, just like natural law of selection, if people are dumb enough then congratulation they are eliminated.
It is ruthless, but that is capitalism for you, look at trading for example, many people try to earn money in trading but it is speculated more than 80% of the people lose money in trading so this means that only the top 20% traders make any money and only the most exceptional traders make any significant amount of money, it is brutal but only those fit to be traders can prosper under those circumstances.
