It's true in my opinion too, there are indeed many altcoins whose functions are unclear, so I don't buy an altcoin that is not clear or I don't know the function of the altcoin, but we don't know what the developer means to launch the coin. the plan that we don't know is that the circulating altcoin based on coinmarket can reach thousands of altcoi, how can we choose the coin, if my experience as a trader I prefer altcoins that already have names in the crypto world and I use those coins as my personal needs , for example Ethereum, I invest in ethereum and also trade in ethereum, besides ethereum I also have other altcoin trading which in my opinion has high potential in the future
