It depends. Even if Bitcoin miners are successful, it’s not clear that their efforts will end up being profitable due to the high upfront costs of equipment and the ongoing electricity costs. The electricity for one ASIC can use the same amount of electricity as half a million PlayStation 3 devices, according to a 2019 report from the Congressional Research Service.
One way to share some of the high costs of mining is by joining a mining pool. Pools allow miners to share resources and add more capability, but shared resources mean shared rewards, so the potential payout is less when working through a pool. The volatility of Bitcoin’s price also makes it difficult to know exactly how much you’re working for.
