Bitcoin and ethereum are the leaders of cryptocurrencies and therefore the whole cryptocurrency basically repeats the price movements of these coins, and above all bitcoin. It is enough to have these two coins, which will further serve as an indicator of the profit of all cryptocurrencies. Of course, almost every coin is individual and therefore their price may slightly differ from the bitcoin price trend. Litecoin is also a promising coin for growth and therefore a certain amount of these coins in your wallet will never hurt.
