Recently, I discovered an interesting cloud mining platform called AutoHash. They previously ran a promotion offering new users free Bitcoin mining credits, roughly around $100 . I tried it out, and you don't need to buy any specialized mining machines; you can operate directly on your phone, which is quite convenient. They say they use green energy sources like geothermal and hydroelectric power for mining, with hash rates reaching up to 1.100 TH/s. The platform offers different levels of mining contracts to choose from based on your needs. What attracted me the most is that this free credit doesn't require any upfront payment, and the earnings can be withdrawn directly without many restrictions. If you're interested in Bitcoin mining but don't want to invest too much, you might want to try their free plan first and get a feel for how cloud mining works.
