Bitcoin, ethereum, xrp, and bitcoin Cash this we're the only coin that I was holding that has a real value in the market, I have a lot of old coins in my mew wallet I got it from participating in the airdrop and bounty campaign most them are shitcoin or no value in the market.
I think the top altcoin currently available is a coin that has been around for a long time. in addition, bitcoin and ethereum are always discussed whether it's for old investors or new ones. I honestly feel that every crypto user will have at least bitcoin or ethereum in their wallet. Well, as far as I can see, the two coins are always held in the long run.
Old projects will certainly produce coins that are useful in the future and even continue to develop in high-liquidity exchanges so I think old coins are worth holding for in the long run.
The current project may not necessarily produce good coins and even tend to become shitcoin after entering the exchange.
