Not possible unless you ve got really, really cheap electricity.
Cause there s nothing to prevent people to buy 120000000 rigs by mid 2018 and bring you out of business. We ve seen this before, in 2013/2014, market gets saturated and everyone shut down their rigs. The ones who remain are people with 6 cents per kwh and lower.
not true you can do good with 20 cent now and more,
in 2018 the profit will be much higher, so evne with more gpu there will be the same profit, while it's easy to double the gpu when they are few of them it's more difficult when you have millions already o the market
I bolded the part of your quote above that always gets me with these counter arguments. If you guys believe so thoroughly that the price of coins are going up so much within 12 months, which is by the way the only way that your future mining profitability scenarios make any sense, then why not just buy the coins directly now?
The OP was talking about investing $300k in mining equipment in the hopes of a 17 month break-even, which by definition is relying on the coins he mines to increase in value. So in 17 months time his plan is to get his money back while in a parallel universe his alter ego is taking that same $300k and buying the coins he is interested in directly.
Since both scenarios require the value of the coins (either mined or purchased outright) to increase in value, the smarter parallel universe version of himself just sat back and relaxed and made a nice profit off of his investment.
The miner version of himself (this universe) meanwhile put in a lot of work, suffered through the heat, noise, rig lockups, changing software, drivers, and all the other mining headaches for a long 17 months and is maybe back to even. Also, since he paid for power and depreciation on the equipment, his investment in hardware is not even worth $300k anymore, maybe half that at $150,000.
