Cryptocurrency is expected to be the future of currency. Recent research shows that the mining revenue of popular cryptocurrencies is way over $21.3 billion with Bitcoin carrying the lion share.
Of the total mining revenue of $21.3 billion, Bitcoin (BTC) accounts for up to $11.3 billion. This is more than the combined mining revenue of all other Proof-of-work (pow).
Ethereum came second in the list as it accounts for $5.8 billion of the total mining revenue which is 27%. Next in the list is Zcash (ZEC) which accounts for just 5% of the mining revenue.
Others topping the list are Litecoin with $1.1 billion and Bitcoin Cash (BCH) with $911.6 million. Monero (XHR) also made the list by accounting for $365 million in mining revenue.
Another interesting discovery from the research is that a lot of miners made quite a fortune solving empty blocks. The research shows that miners made up to $335 million solving empty blocks, with Litecoin been the highest rewarder. The good news is that the number of empty blocks has reduced drastically in 2019.
