Yes. When I turned on my 1st newbie miner on October 18th, 2013, Bitcoin at least 'some-time' that day was $150.00 even when I looked and I made about
1 BTC a day....Well, the price to just have the equipment to make 1 BTC a day is 'supposedly' by the math: $4,500,000.00 USD investment.
If that does not tell you 'big farms' are not the future, not sure what will. The big farms also probably by now need 2c-3c kWh electric 'at least' to boot!
You are comparing the price to make $150 then against the price to make $35000 today. How much would the equipment cost to make $150 today, or $35000 then? Those would be fair comparisons.
