Nowadays, Bitcoin mining is a specialised business and not profitable for everyone. Therefore, we strongly encourage anyone interested in mining to do his/her own research and make the necessary calculations before investing any money into the operation.
The most important factor is, of course, electricity prices. For the majority of households, prices are simply too high, making Bitcoin mining unprofitable. You can check the current break-even electricity price for every popular Bitcoin ASIC with our Cost to Mine 1 BTC tool.
