Bitfarms, one of the largest BTC miners, posted a 140% increase in the first two weeks of January, followed by Marathon Digital Holdings Inc. by 120%. Hive Blockchain Technologies Ltd. Its shares nearly doubled in value in the same period while the MVIS Global Digital Assets Mining Index rose 64% in the first month as well.

The Luxor Hashprice Index, which aims to quantify how much miners can make from the processing power used by the Bitcoin network, is up 21% this year. This partly reflects greater rewards due to the increase in the price of Bitcoin.
