Topic: I want to invest in 20x S7 (Read 3463 times)

It takes time, as soon as you play around with the miners for a week or two you practically know everything about miners except the most technical parts. Not super easy to learn, but not impossible or too difficult either. There's always the forum here to help too, just ask when you need to

you'r not alone bro

Me too 

i dont unstranded any thing in mining

today DHL has delivered our 7xs9s.
The server room is on it's way to finish, cabling is done shelves are left.
After a while I'll provide pictures if you are interested.

hey bud, I want to get rid of one of my ones

as soon as s9 will be available on bitmaintevh we decided to buy 7 of them, atm investor is my friend

Is it the price drop? but its 533 USD for me on the website

If you want to get in now just a bit over 2 months before the halving you can but expect your profit to drop to a +-1/4 at the halving of what ever it was the day before
that being said there are pros and cons there should be a market lag on the bitcoin price to increase after the halving how high no one really knows it really depends on demand
so if there is a price increase lag "IF" then we suspect the price of miners to go down hopefully to half first who knows... and it would be easier to sell the 28nm chips cheaper as im sure
they have recouped their RnD costs than to jump into 16nm chips which would be way more expensive possibly double in cost for the same Hash... one thing is for sure the hash rate
of the network will change... how much...??... maybe 10% down definitely not 30% down as most of the miners contributing to the hash rate of the network are S7's yeah we got bitfury and spon
but have a look and the history of the network hasrate and difficulty and how is jumped since nov15 and jan16 and this was due to the S7's coming into the market.

but your guess is as good as mine.
one thing is for sure interesting times ahead

So much depends on electricity prices to.   Even the "bigger growth" for the mega farms paying just a few cents on electricity.... still made profit.  So it's all about that electricity price currently.

I hope it changes a little when next gen first hit's.  Hopefully home/hobby miners get a little better shot with better efficiency.  But it is likely the mega farms use the new gear to.. so could be moot.

If I think I can get to break even at 6 months to 8 months I go for it.
A lot depends on power price.  With the solar array agreement I am in my power is low.

Every one looks at those 20 % jumps back in the winter and gets afraid.

but we have four sets below  how can you tell if this small growth time right now will be really long or short you can't

thus  saying 2 to 4 month roi   is your good point  may be wrong.

power price is key  he is at 6 cents.  so he could go  longer then 2 to 4 months.  maybe 5 to 7 months.

I will say this  he should go slow to start but he should try some gear. even two s-7's and 2 psu's won't kill him and he can learn how much work it is to mine. In house.

Even in the former case, it was a horrible investment. ROI in 2-4 months or you do not do it.

And phil has a good point about being diversified.   If you put all in one part of Bitcoin ... could be great but also it could cause a quick loss.   I  split mine between gear and coins mainly.   Cash I mostly use to pay electricity bill as it is not cheap.   So not keeping in cash could come back and bite me, but I'm taking the risk.

Also just because you invest in miners does not mean you can't sell one day and buy BTC or new miners.  I sold all previous gen gear as I made far more off sales then I would mining at my electricity rate.  I sold and bought BTC.  So it worked out pretty good for me.   So you can always sell gear, only thing is when next gen hits current gen likely go down in value (hard to say how fast).

But I still suggest doing a few miners vs all out.  Maybe 5 then 10 then 20, just space it out to give yourself time to make sure everything works right. Especially with summer coming.

Well it is a game with risk. No one knows the market once the ½ ing comes.

Your have a good power price 6 cents a kwatt.

It comes down to this can you afford to lose 4000 usd ? 

You won't lose all of it if things go bad.  4000 usd would get you in and help you learn.

you need to understand this game is like the tide it has highs and lows.
You can go safer then buying 5. 
You can buy 2 with 2 psu's before the ½ ing.  learn the game a bit more.


My money is spent on this method  with btc..   ⅓ is in coins ⅓ is in gear ⅓ is in cash

I understand the risks and If I'll decide to do it I'll start with min 10.
I'll post whatever I will decide, thank you all for your time and advice, wish me luck

On having... just google and you will see countdown clocks (they are not 100 percent accurate, but they give a decent speculation).   But honestly you will have to decide on your own. You have all the facts at this point it is just if you want to make a risky investment or not.   You could look like a genius and gain a lot... or lose it all in worst case.   There is no guarantee  of profit.

Also I would start off with fewer as in a couple just to test place out and see how it works.  I would hate to buy 20 and figure out electricity is not ready, or cooling needs big adjustment.  Going full in at once is normally  not advised.

OK now it made me to think a lot, halving will happen in about two month or so right?
If it would happened in 1 year or so I would be buying miners right away, but now it's little confusing to me. If I was counting on ROI for 10 month~ now it became twice as large if the price will be same after halving.
First I was thinking to buy 15-20 units, after that I saw halving is so close I thought 5 units would be better choice as Phill said, but now I'm confused. Mine or not to mine..
Any advice would affect the decision I will make in next few days

with all fees and taxes, the only thing I have to buy is 25kw cable which will cost around 50$ that's it

is .06 your base rate or your rate with all fees and taxes, etc?

First don't use slush  use kano

check out how poorly slush does to kano


Second  the ½ ing   means a block reward will drop from 25 coins to 12.5 coins.

a few simple facts no one knows what the effect of this will do to the price of coins or the difficulty of coins.


but  math wise  we do know that 25 coins reward will drop to 12.5.

I am 59 years old and an optimistic type guy.  But I read your  power price is 6 cents at 6 cents you are good not great.

I would not buy a lot of s-7's in your case.  i.e. do not get 20.  order 5  and order 5 psu 's  direct from bitmaintech.  When you have a bitmaintech account I will send 5 coupons to you for free worth 500 usd.

your cost will be reasonable  maybe 4k  with the high shipping and you are in the game.  After the ½ ing you can assess what to do with you extra investment money that you held back.
