we can't see everything just by looking at the rankings on the market cap.
all assets are determined from market demand. We have seen many old assets already in the market but not getting good enthusiasm from the community and the market.
It seems you are starting to misunderstand what I mean, look at the coins that rank well in cryptocurrencies, is the volume and demand for those coins bad? and do you know why Bitcoin and Ethereum can rank well in cryptocurrencies? looks like you have to investigate that first so you understand why they both can be in a good ranking, because the ranking is not born by itself, but is always determined by demand and volume in the market.
