Bitcoin mining as a hobby can be fun and even profitable if you have cheap electricity and get the best and most efficient Bitcoin mining hardware.
Bitcoin mining is competitive. Until recently, it’s not been ideal for the average person to mine since China’s cheap electricity has allowed it to dominate the mining market. But that has changed since China outlawed mining in their country. Even with this recent change, if you want bitcoins then you are better off buying bitcoins.
