13 November Break Even Rates For: BitMain S9 / WhatsMiner M3 / Ebit E9

[Isaac_]

Hi,

I did some math for comparison. There is also links to the companies currently selling profitable miners.

COMPANY              SHIPPING DATE       PRICE          ESTIMATED BREAK EVEN AT €0,06 /KWH

Please note, that these prices include PSU and shipping.

bitmain            20-31/01/2018    1600 usd         May
whatsminer*      20-31/01/2018   1200 usd         april
ebit / ebang      20/12/17      1250 usd         May

*seems legit due to this review

You're not factoring in difficulty increases and electrical costs, so seems like the break even is very optimistic.

For example the Whatsminer is pulling 2kw - that's 48 kwh per day, or $148 a month at 10c/kwh.

Good point! Thanks! I was using cheap (but not extremely cheap) electricity as measure. I will update my post for higher accuracy. Edit - updated! Hope it's better now. It seems the WhatsMiner is the best choice right now in terms of breaking even as fast as possible.

Edit 2: There is a very obvious general correlation between difficulty and price. Look at these charts:
https://bitinfocharts.com/comparison/bitcoin-difficulty.html
https://bitinfocharts.com/comparison/bitcoin-price.html

I see nothing overly optimistic at all. BTC will most likely go up long term making previously mined coins even more profitable.

Let's also not forget hardware STILL has value, even sold at 1/2 the price of purchase, this would bring you to break-even in total liquid assets 6-8 weeks sooner. Once you truely broken even on costs, you are at a profit, since you have hardware you can sell onwards.

I, for one, will probably buy one based on the review, just to make sure Bitmain gets some competition. If I like it, I'll buy more.

If you calculate in a modest 4% increase in the difficulty, it pushes breakeven out to mid July with .10 power. And going obsolete when the Difficulty reaches 4000G.

Another factor to consider is infrastructural investments which might need to be made.  If you're only planning on running 1 miner and you have a free circuit then great!  But if you try to add 2nd miner it's not going to happen @2000W so I hope you have a 2nd circuit free or you need to factor getting an electrician to install a new one for you.

Really, if you are currently considering buying any of the currently available 8+TH miners at home, think again. Especially @110V . They are too loud, too hot, too power-hungry to do so. They need to live in a hosting facility with the lowest power costs you can get.

Most miners of this particular generation are going to have an extremely slow break even with small difficulty increases factored in and an electrical price of $.10/kWh. I’d suggest possibly waiting for another generation of miners to come out at ten cents per kilowatt at this point. Even at $.065/kWh (my cost) I’ve held off on buying miners and I’ve actually sold off most of mine due to the huge difficulty jumps we’ve been having recently. Considering whatsminer managed to bring about a very reasonable improvement to efficiency on 28nm there’s likely still room for improvement on the 16/14nm process.

Electrical wiring in your home can be a big issue for home mining and that in itself is a big investment if you can’t do it by yourself. I have a buddy who’s an electrician who did the circuitry in my house for pretty cheap, but I know nowadays it can get very expensive.

4% per difficulty period nowadays isn’t too realistic, increases can get to 10+ and even more with more and more miners being pumped out every day.

I wouldn't run it at home, at least not long term. It would definitely be destined for my hosting facility. I would run it here at first to test it and see if I like it. It's pretty heavy on the power, so I'll run it from the dryer circuit. But I run very little gear full time at home, an R4 in my home office that's doubling as a space heater and Ebit E9 in the garage since they don't draw as much power and are on different circuits that keeps the garage warmer on the cold mornings. All of my other gear is hosted.

I'm not crazy about the efficiency. It's great for a 28nm miner, but doesn't really compete with the current 16nm gear. But I believe we have to support smaller manufacturers, or we are going to get stuck with more of the same from Bitmain. I am willing to buy and run one of these, even if I only break even on it. Though with my power rates it should ROI in less than 5 months.

I am totally going to look into those whatsminer thanks for sharing!   Cool thing you did here thanks!

Where are you hosting at where you can get ROI in under 5 months and still has capacity?
