Although Bitcoin is still the dominant cryptocurrency, in 2020 its share in the market capitalization rapidly decreased from 90% to 65%. Such a scenario was predicted by many experts, based on the growing popularity of Ethereum and the smoldering conflict in the Bitcoin community over the block size. If you want to invest in cryptocurrencies today, Bitcoin is still a traditional element of each portfolio, but it is no longer a key asset. In each well-balanced crypto portfolio, you will find coins such as Ethereum, Ripple, Litecoin, Dash, Monero and others.
