Of all the coins in the cryptocurrency, Bitcoin is the king of all coins, currently 1 bitcoin equals over 64,000 dollars. And the price of Etherium is about 4,000 dollars. Ethereum's popularity is second only to Bitcoin's but there are many differences if we look at the price. I believe the Bitcoin price will never surpass the Etherium price. The world’s highest could exceed $6,000 by 2021 but the Bitcoin price is likely to exceed 100k dollars.
