If you want to mine altcoins with video cards, first read the following analysis (and may be you'll quit that idea altogether).
Since mid June profit from 1070 GTX in 5 weeks dropt by 3.35 times, following the drop in the price of ETH by 1.49 times and the difficulty rise by 1.82 times. So the ROI period for those who would pay $3000 to make a build with 6 GTX 1070 in the end of July rose to 9 months, and should the difficulty keep rising with the price of ETH staying where it is now or dropping, multiply that 9 month ROI period at least by the factor of 2, which gives us one and half years only to break even on the money spent on equipment (and that is in the best case scenario – if the prices of crypto currencies you mine rise sharply).
Not a bad tactic at all for the computer manufactures to release new GPUs at the prices 50% higher than they could have and then within a year pay miners those 50% via a certain altcoin – just to keep the mining rush going.
And before you call me a conspiracy theorist, think that as of now ETH network has hash rate of 72 138 000 MH/s, and one GTX 1070 produces only 30 MH/s, that means you need 2 404 600 GTX 1070 priced $400+ to produce that 72 138 000 MH/s, that is $1B, $330M of which where spent on GPUs since this video was uploaded 5 weeks ago – to achieve 25 000 000 MH/s increase in the ETH network hash rate. And while GPUs factories received a cash inflow of $330M, they have paid miners for the new GPUs that added extra 25 TH/s to the ETH network around $39M.
With difficulty of mining ETH growing each day by an average 1.68%, in one year from now those new GPUs will get additional $112M for mining, and some minor $256K after that, before mining ETH on 1070 becomes impossible. So in total we pay GPUs producers and retailers $330M to get from the mining only $150M (unless during the next 365 days the difficulty growth will slow, or ETH price will rise significantly)…
You say no way, I say – buy silver bullion and stay away from mining. Stop wasting fresh water that is needed to get oil from the ground (which is used to produce electricity) and feed those smart asses in charge of AMD and NVidia, sacrificing your comfort for nothing. The running of only one GTX 1070, consuming 150 Wh, makes disappear 10 liters of fresh water monthly.
And if you think you’ll be fine in ZEC, keep in mind that its difficulty is growing at the same speed with the difficulty of ETH. The only way you can get substantial profit from this new HYIP is buy cheating others in to it and by selling to them your expertise afterwards. But there is nothing noble and honorable in doing so (as the crypto currency advertisers want us to believe), isn’t it?
Cause with the current difficulty growth the mining of ZEC & ETH will become uneconomical in 5 months, since you’ll be paying more for electricity, than getting from your cards (and will get back only around 20% of your original investment, if you sell the altcoins the day you mine them, without waiting for their price to rise fivefold – just to break even).
If you found some fatal mistake in my thinking, do share your based on real numbers opinion on this matter.
