BTC, ETH, ADA, SOL, and MATIC. I think these are 5 best crypto coins for the main investment in 2024. But to have additional investment, I think we can choose the hype coins or the coins with cheap prices. However, make sure the coins to have good daily trading in the exchanges. Simply ignore to buy the new coins with low trading volume daily. It seems the interest of the coins are low, it may not last a long time in the market.
