Odaily Planet Daily News Bitcoin mining company Marathon Digital (MARA) failed to meet first-quarter revenue expectations due to operational challenges in the first quarter. The miner mined only 2,811 bitcoins in the first quarter of this year, a 34% decrease from the previous quarter. The miner's stock price fell by about 1.5% in after-hours trading on Thursday. The miner said in a statement that Bitcoin production and revenue this quarter were negatively affected by unexpected equipment failures, transmission line maintenance, and higher-than-expected weather-related power restrictions in Garden City and other locations this quarter.
