We know the setup for mining a bitcoin will cost you a lot now, so do you think instead of buying a setup just use the fund to directly buy bitcoin?
Buying a mining rig today is profitable if you mine some altcoin and then dump it in the exchange. Mining bitcoin is not profitable as it was like 5 years back and so I dont recommend it. Since bitcoin price has dipped it is a good time to buy bitcoin and hold it. BCH may be up but it is being pumped by the whales and it will soon crash.
I would just decide to buy a bitcoin and stay cool as its price has tremendously increased in the past months.Before investing in mining,we have to consider lots of factors.Main factor is that we have to ensure cheap electricity.Otherwise,it would be useless to buy an ASIC miner and mine.It would be a total waste of time otherwise.
Electricity may be cheap but the mining ROI also depends on other factors. There are countries where electricity is cheap but they are not flourishing in the mining industry- why? because setting up a mining farm and the engineering costs are too much for them to incur.
