As of 2021, the highest-value cryptocurrency by market capitalization is Bitcoin. Bitcoin was the first decentralized digital currency and it remains the most widely adopted and valuable cryptocurrency in the market.
Bitcoin’s market capitalization has been consistently high and it has reached an all-time high of over $1 trillion in early 2021, making it the first crypto to reach this milestone.
This is due to the fact that Bitcoin is considered the ‘digital gold’ and investors see it as a store of value and a hedge against inflation.
As the cryptocurrency market is highly dynamic and new technologies are emerging every day, there is no guarantee that Bitcoin will remain the highest-value crypto by market cap in the future.
Other cryptocurrencies such as Ethereum, Binance Coin, Cardano, and Dogecoin have also seen significant gains in recent times and may also reach high market capitalization in the future.
