Topic: Bitmain Launches Antminer S9 Hydro - page 2. (Read 1534 times)

Seems like a cash grab to sell off the rest of their old S9 parts. I bet they wish they had Yang Zuoxing back.

yeah, we seem to have the same "problems" ;-) at home ...

Trading cash for power to receive BTC is always a win. Mining altcoin for profits? Be careful with those bags.

I clowned this asic talking with sidehack calling it a CPAP machine. The concept for hobbyists is on point, still not a novice asic. Some say neither are the industrial style but I'd probably start with a cheap s9 or 8 series canaan still.

I think fanatic called it on the other thread, that no farm is going to house these by the 10's of thousands. Though putting 1-5 of these in house would be better for the wife at home and much easier for sound management with all the sealing and acoustic absorption I've done.

Happy wife happy life.   

If your goal is to mine regardless of profitability, or to make hot water via electricity at reduced cost, this miner is acceptable.

If your goal is to end up with more money (in whatever form) than you started with, this miner is not acceptable.

You're not accounting for that BTC and cash are directly interchangeable. One is the other. That's the whole point of currency. Trading 1BTC for a BTC-making machine that'll only make 0.5BTC is a net loss no matter what currency you started with, unless the heat it makes is worth more than 0.5BTC to you. And that's assuming the substantially increased mechanical complexity doesn't fail first.

but he is wrong since the reality is I am using cash  not btc to buy the miner.

The fact that I buy whatever in btc  and don't hold the btc has nothing to do with my hodl btc.

He fails to separate and understand he is using cash  and btc has nothing to do with the purchase. Other then as an envelope to deliver the cash to bitmain.

He fails to understand that buying gear and  mining is a completely different animal  then buying coin and holding.  huge issue for me.

He fails to understand that a 45gb miner has $$$  to some as a good space heater.

Myself I can't use this as they lack efficiency of the T2Turbo  and cost 2x that of the standard s9.

I use the tradeblock.com calculator to give me an idea of what the miner will bring in given average changes in diff/month to see my break-even and profit in a year. I usually use 7% diff increase/month (which I should probably increase...) and if I don't see ROI in 6 months, I don't buy the miner. For me, the profit motive portion of mining to acquire more BTC over time than I would receive if I bought BTC with USD or simply held.

So long as mining will net me more BTC than I otherwise would have, ill keep investing in miners/upgrades.

I think what he's saying is, if you have 0.3BTC and $2k, you could buy another 0.3BTC with that $2k or buy a miner which, over the next two years, will mine you about 0.2BTC. End result being, if you want more BTC you're better off buying BTC than this miner. Especially if you're looking for a boom in BTC pricing, since with booms come higher diffs which means a lower reward. 0.6BTC now is better than 0.5BTC in two years because 0.6BTC now can *still be* 0.6BTC in two years, guaranteed, while that 0.5BTC is a speculative best-case.

If you're planning on electric radiant heat in floors or a pool, this miner might be a good investment. But if BTC is your primary goal, I can't envision a situation where this machine is worth buying.

what does it have to do with btc.

I have 2000 usd
I have .3 btc

I buy btc  with the 2000 usd.

and buy the miner.

my btc stays the same.

.3 btc

my cash drops.

So you are saying buying a miner for 0,22 BTC that DOES NOT make 0,17 BTC within 2 years is a great investment?

Well, this is where I pass...  I will NOT buy any miner if the amount of BTC (or BCH, LTC or ETH) is -lower- then the BTC, BCH, LTC, ETH I allready own.
Sorry, but it the most stupid thing you can do with your Cryptoś right now...

Investing and not gainging the amount of BTC you pay  Maybe I am stupid, but I don't get that.

Be me guest, if bringing your BTC to lower numbers then you allready own is your goal.

Unless your looking forward at a higher price for bitcoin in the future.
Not everything is about the now profits..

Seems, nobody is willing to do the math...  It is a worthless piece of shit even with -free- energy...

18TH mines 0.0007 BTC a day x 365 days = 0,2555 BTC a year without diff and hashrate going up.
Roughly every year the mining power triples, so 0,2555 BTC \ 3 = 0,0852 BTC a year taken in the diff and hashrate rising.
(Again, I do not count energy. Presume you have this free for this calculation)

Even mining 2 years = 0,0852 BTC x 2 = 0,17 BTC mined in 2 years (not even mentioning the diff and hasrate rising in 2020!)

Costs of the miner are (for me in the EU with VAT and import) +- 1300 euro (without PSU) = 0,22 BTC cost of the S9 Hydro right now.

Simply said; You're better off keeping your BTC in your pocket and skip this garden hose miner

Residential - yes, but not that good in a hot climate. Those large radiators are harder to vent outside than a plain S9 with some ducts. But works great in a cold climate during the winter - free quiet heat.

i think it is actually superb...
If you have a cool water source, you can run them silent and efficient, and even recoup the energy in form of heat, which usually goes out the window.

i love it, and i hope to aquire some very soon.
Now, improve and upgrade to 30Th as the competition does curently, and i'm all ears...

There are easy well know solutions to keeping water effectively biologically inactive.
Using distilled de-mineralized water would be a must... and UV is very effective at keeping it biologically inert.
But since water is rather resistant to heat absorption..Glycol AKA "Rad fluid" would become the standard substitute pretty quick I imagine.
Though there are also some more exotic more effective liquids.
But then you are dealing with a closed system that must have fans and airflow and ventilation all over again. Bye bye to your electricity "Savings"

You are correct in noticing the electrical efficiency will be minuscule.
Reliability and service life should increase dramatically...but will probably not offset the huge increase in maintenance costs.
Pumping high volumes of air is always going to be much cheaper than pumping water
And there will never be a better solution to heat dissipation than using mother natures free cold from extreme Northern/Southern latitudes and simple convection.

Further I would speculate the actual added volume/space requirements would be another huge cost for large farms to replace and modify the set-up density.

Bottom line is this a short sighted gimmick. It only give the illusion of increased efficiency.
From a total engineering perspective it significantly increases in-efficiency and risk.
Looks like it was designed to target small scale residential market of hot climates

18th's at 1700w isn't a game changer. Plus think of the downtime scrubbing scum from tubes will bring.

This is only the last place for that info because some saboteur overzealous moderator quickly deleted at least two threads on this machine since Thursday.

As usual this is the last and worst place for info on crypto gear.

Too bad so sorry but you engrish long nose round eye's can't buy it.

Only for China market first....later you suckers can have ...after we take most profit first..
