We aren't done with trash coins yet until we realized that bitcoin is the only solution provider to this, aside bitcoin in cryptocurrency, other coins are altcoins, there are also a number of shitcoins that constitute same, but there's a way we can also invest on some prominent altcoins from the list of best rated ones starting from ethereum and few others we can choose to go for if we have the experience and the ability to risk on them.
Just choose the altcoins that you know and believe will someday grow or as you've said, the prominent ones. We've got a lot of them and it's your choice on which is going to be your pick. There's lesser risk with them and that's gonna make you like Bitcoin because it's always been the stable crypto in the market. Stable in that sense that you've got assurance that it won't be rugpulled unlike the choice of many folks today, meme coins, NFTs/tokens, etc. Too rampant in that scene.
