The first bitcoin miners were able to earn coins relatively quickly just using what computing power they had in their homes. Double check the team who are running the company. And if you want to bet on the bitcoin price going up, you can simply buy bitcoin and save yourself the whole mining hassle. In some cases, you might be required to sign a year-long contract, locking you in. Note that I put the power consumption and cost per KWh to zero since they cover those costs. Is it just a fad or could Bitcoin genuinely develop into an everyday currency?
