    Mining industry


    Bitcoin mining profitability

    The mining revenue decreased to $0.25 per 1 TH/s, from $ 0.33 two weeks ago. This is due to the price action and high level of mining difficulty, causing fierce competition among miners. It’s been more than 4 months since the price per 1 TH/s has been at this level.

    Bitcoin mining difficulty

    The Bitcoin network witnessed a significant difficulty increase of 8.33% on December 11, 2021. Despite a minor decline of 1.49% in the last two-week cycle, the trend remains positive and has been moving upwards since the end of July. It’s at nearly the same level of difficulty ATH as during the middle of May when it was 25.05 T.


    Ethereum hashrate

    Like Bitcoin, Ethereum mining is experiencing hashrate growth this month. Its highest average hashrate of 932,658.5 GH/s was recorded on December 14, 2021. With combined factors of the price dropping and hashrate climbing, the current unit revenue of Ethereum mining is around $0.064 per 1 MH/s—compared to $0.075 at the beginning of December.

    The network just crossed 1.21 million ETH burned in 132 days since activation of EIP-1559, with a burn rate of 6.28 ETH/min, offsetting issuance by 0.62x. During the most recent 30 days, ETH transfers rank top on the burn leaderboard.
