https://coinmarketcap.com/currencies/coinweb/ Is this what you mean? I think that they are quite worth investing in but some I have noticed they are not as popular in any circles so they have a high risk too.
If you want to invest here for the long term, I think you should consider it as you can afford to lose the money you invest.
They are not traded on a big market like Binance, but are listed on some quite big markets, I think they do have long term potential, but I am not a financial advisor, you have to do it at your own risk.
