Topic: Bitmain's Released Antminer S9, World's First 16nm Miner Ready to Order - page 345. (Read 531164 times)

I really hope they release the next batch soon, because I have already started selling my S7's and was too slow for the first batch

It looks like I'll cover 75% of the cost by selling 3 S7's  -- So it is a no-brainer  -- if I can get stock

Sure you probably make more by just buying and Holding BTC ,,  but where is the fun in that

I don't think so... The process isn't available since that long.

First batches are small to allow them to fix any unseen issues and still ship out on time. You'd be more annoyed if they committed to 50,000 units day 1 then had to delay delivery, right?

Never heard that before, but worthy of consideration and might explain the number of iterations and selections that the S7 went through?

Any more info on the rumour?


Rich

has anyone heard the rumor that the S7's chips were in fact failed runs of these same 16nm chips.. for fear of being called a failure bitmain decided to market the s7 as better fully customized 28nm

interesting theory

Miners have repeatedly shown a willingness to invest and operate even when ROI is obviously impossible, in the hope I assume that BTC prices do a moon shot at some point in the future.

Yeah I'm thinking they have had these for awhile and were waiting for bitfury.

Haven't we learned yet to just buy the coins and hold.  Even if it takes 2 4 6 years for it to rise.  At least your not competing with diff.  If all holds true price will keep rising as supply shortens.  But the miners don't have life expectancy of much over a couple years.  And they sure aren't  built to last for much more than that.  So that begs to question why keep doing this over and over. Definition of insane is doing the same thing over expecting dif results.  That huge show of force on the network was no fluke.  Everyone speculated with the s7 that network would drop.   And it did what ??  Went to the moon. And the more I look back at it. The increase was 3x. Which aligns nicely with the s9 efficiency. Not the s5>s7.  So it seems maybe they have the s9 sooner and sold us s7 so they could easily squeeze us out.  The game seems well in hands of bitmain for the time being.

At this point isn't it wiser to just hold the coin and wait for the price rise rather than risk the hardware bubble popping?

How's the profitability on this one? I'm no longer buying these bitcoin miners for they hardly ROI. Difficulty change, halving, decreasing price of hardware, etc makes mining so inconsistent nowadays.

Based on historical trends, how much longer before B2 is released?

this is accurate. 

400ph is old stuff.
It dies in July.   
Bitfury has nothing  for at least  a month.

So from now until August bitmaintech  will slowly sell s-9's  making big profits on high markups.

Once other companies start to sell better gear bitmaintech will cruch them with price drops.

Early s-9 buyers should do okay from June 15 to Sept 15.   Then the diff will move

Nah, game not over for Bitfury - their announced efficiency for their chip is competative.

 On the other hand, they DID take too long getting to market, so they're going to HAVE to compete when they do finally get something out there. No "first to market" bonus gouging pricing for THEM!


 Bitmain I figure will drop the price quite a bit once someone actually DOES release a competative product - I can and WILL wait, $2100 is too much IMO even with the hashrate and efficiency.


 If you assume 3% or so hashrate growth, I suspect you can get that 7-8 month ROI - the halfing is likely to KILL a bunch of older miners due to massive unprofitability even at VERY VERY cheap electric rates, and so will likely see a substantial dip for a while - the S7/A6/BEleven units should stay profitable if your electric is cheap enough, but SP20/S5 generation forget it unless you have FREE electric I'd bet.


 I'd NOT assume network hashrate growth in July.

They only listed the S9 on their English site, so probably stupid Westerners.

What's a looser?

For the loosers !!!

I'm curious how some people are getting a 7-8 month roi when they run the numbers. My assumption is that they are completely ignoring network growth? Possibly using calculators that use present day difficulty and 25btc block reward.

If you look at the 2 month, 6 month, and 12 month average for growth per adjustment interval it's clear that we should anticipate ~6%.  To assume 0 or negative (I saw some assuming -30%!) is completely baseless and not supported by any empirical network trends.

This is really the only tough variable. Running the math with 6% growth returns an roi period of more than a year... With free electricity and a free PSU (quite a few of us likely have a PSU we could use so that part isn't too much of a stretch).

Add even the most stellar electric rate of $0.035 (3.5C) /kWh and roi is mathematically impossible. After about 500 days you are still in the hole for about 1btc and never hit 0.  Now I assume some people will count the resale of the hardware. That's fair, what would you expect to get after 1 year? After 500 days??

So I went back and adjusted the growth to 4%. Not likely, but certainly a high enough probability that you might want to take the gamble.  At 3.5C/kWh you're still looking at 10 months to roi. I guess the unit would still have enough value at 10 months for resale... If the devaluation of the S7 is any indication maybe 0.5btc.

Now there is a bit of reality to contend with. Shipping isn't free and you'll likely have to pay either customs fee or VAT depending on location. If those 2 don't eat up your 0.5btc profit the power supply certainly will.

Basically if the stars align you get your money back over a year later. If even one variable doesn't work in your favor you lose your shirt on the deal. And don't start with the value of BTC rising after the half. If we are considering BTC increases I would simply purchase BTC and hold onto it. No need to pollute my environment with all the heat and noise at that point.

So that begs the question, who is this marketed for?

What did someone quote here you can get 3 s7's for about 400 bucks plus less then the S9....

my issue is the 90 day warranty...I'd probably do the 3 before the 1 ..because if that S9 bricks out after 90 days you'd be out the works

(this is outside the question on if it was worth getting or not..just another side angle to consider)

That's a hell of a gamble
With the current used prices of the S7, I can't see buying the S9, power is only at 6 cents for me..

Had they come in closer to 1600 I'd of bought out my 5.

I had 43 x S7  have left of less than 30

Most of the time I used Nicehach and Antpool.  Antpool luck for last 3 monthts is 103.00% , total 101.00%
No down time at all , may be a total of 5 hours.

I do not consider the price of the PSU , I almost never sell PSU-s with old miner.
Postage and VAT is calculated on the price of the miner.
I paid first for  electricity from my  savings and I kept BTC

I sold BTC only at the end of last month. Previous sales were at 420 euro In January this year.

I bought 10 x S9
9750 EURO + 19.862 BTC
Add VAT about 4000 euro  and I still hope  to come to profit.
