There are few cryptocurrencies other than bitcoin that will be Monero, Ethereum, Litecoin and so is preferable for me.
I wonder if there are the most important cryptocurrencies, why are there so many of them? Then people would only invest their money in important coins. It seems to me that there is no such thing as important cryptocurrencies, there are promising and stable ones. For me, these are a few of the top 5 coins, after Bitcoin and Ethereum.
most new people who still don't know about cryptocurrency so they can still invest in the wrong altcoin and don't have good potential, but for professional traders who already know and understand cryptocurrency a lot then they will definitely prefer the 5 best coins that have volume trading high from above that from the Coinmarketcap list.
