The cryptocurrency market is being flood with plenty of altcoin of which not all the altcoins are worth buying , so many of the altcoins will end up becoming pump and dump or end up being abandoned by the team behind it.
So many altcoin don't have solid background and even the project team behind them lack reputation in project development. So therefore we should be very careful when choosing crypto for investment.
To me some of my favorite altcoin is Solana, Etherum, Ada ,BNB , floki, Shiba , and pepe.
