Bitcoin miners earned more than $15 billion in 2021
March was the most profitable month with a profit of
$1.75 billion for miners.
Of this amount,
$167.2 million were transaction
fees.
And in early October,
the daily profit exceeded $40 million.
Profit per day
increased by 275% compared to the values that were before the two-fold reduction in the reward for the mined block.
The companies themselves sell the mined cryptocurrency, but there are miners who
save some of the coins.
And the other part is sold to
pay for the costs of the activity.
