Bitcoin miners brought in about $5B in 2019, The Block reports.
As a comparison, the previous year this figure rose to $5.26B, while in 2017 it stayed at $3.19B.
Last year, Bitcoin miners earned a total of $4.89B in rewards for mining blocks - 12.5 Bitcoins for each block mined. The remaining $146M came from transaction processing fees.
It must be noted that The Block's analysts based their calculations on the Bitcoins that were sold immediately after they were mined, meaning they did not take into consideration the profits of those miners who sell their Bitcoins later or just keep them.
The next Bitcoin halving, which will take place in May, will reduce the reward per block mined from the current 12.5 Bitcoins to 6.25. If the price of the cryptocurrency does not rise, this will probably lead to a significant drop in miners' income.
