If we want a big profit in the long run then we have to buy coins that have a strong reputation, especially coins that are still cheap, the opportunity for big profits can be easier for us to get, some of the coins that I recommend to buy and hold until 2024 are matic, Cardano and XRP.
Those are good choices but I still would recommend you add Bitcoin to your list.
The price of most coins move in relation to bitcoin's and I see that in distant time Bitcoin will cross its all time high and now that the price of Bitcoin is still low we could take it as an opportunity to bag more and wait for the market to regain it self.
I have hope that by 2024 the market is going to recover for all that has happened in the past.
