Many altcoins will experience an increase in price in 2021, but I am very confident about 2 coins namely LTC and ETH. I think LTC and ETH are the best altcoins that are part of the top 5 CMC. the price of the two coins will exceed the 2021 ATH. Apart from these two coins, I have high hopes for the LINK and TRX coins. I think it's the current altcoins that catch my eye in 2021. May 2021 all altcoins experience a significant increase in price, so everyone will be happy
