I want to invest in 20x S7

[mettalmag]

I want to buy 20x S7, for one unit I have to pay around 920-940$ (for shipping and bringing products in country which is +18% of total cost).
The cost of the power is 0.08$ and there is a chance of getting some free energy too. In the case of the free energy there is no doubt to buy those.
I wonder how soon would new miners will be available, I'm thinking about 6-7 month for ROI, is that correct ?
I need your advice guys, any ideas and offers are much appreciated

Your math seems to be on the dot, minus the fact the halving is mere weeks away. While the recent price increases bode well for miners after the halving, investing right now is ever so slightly riskier than usual with the reward being chopped in half before you could hope to ROI.

[mettalmag]

there nothing wrong with math, I have to pay 807$ for one miner + shipping is 114$ that would be around 19k for 20 miners plus some unforeseeable charges.
so you think I should wait till the next difficulty change ?
I also wonder if I can use some coupons provided by bitmaintech?

Are you already mining? If not I'd like to say out of personal experience it's not really worth it.

Miners are hot and noisy as f*ck.. Not to mention given the halving of the block reward is coming soon I would hold off.

[mettalmag]

I was mining with old S1 x3.
I know about noise and heat they produce and I have excellent place for them with cooling equipment and lots of power.

ROI is honestly hard to tell you as difficulty changes really can be tough to speculate, this current one looks good.  Also value of BTC hard to predict this period again it's been pretty great.   But not all periods are as good, it's not a guaranteed ROI.  Also new machine no one can say this, that is a questioned speculated on but no anwser supported by fact's that I know of. That being said I still love it and will always mine.

How much free electricity do you have access to?  Does noise/heat matter in the area?  

[HerbPean]

This hurts really bad on the ROI aspect => for shipping and bringing products in country which is +18% of total cost

I would consider to full all the free electricity you can have access to with some S7. You'll minimize the risk and you are pretty much sure to hit the ROI. Don't forget the resell value of the miners when you'll want to turn them off and/or upgrade them.

As for the one you pay the electricity, it's going to take a long time to hit ROI. We speculate that the new gen of hardware will kill a bunch of old one but i'm pretty sure the Diff will just keep rising, even after the havling. But all of this is speculation. We don't know what will happen.

Bitmain's new chip ?
Bitfury's new chip ?
Whoever's new chip ?

A price war between 2 or 3 of them with the new gen would help us a lot. We know Bitmain and Bitfury have huge pocket but hey also have huge farms to run their new miners. A previous price war between Spondoolies and Bitmain proved to be very profitable but it's also due to a small difficulty increase over a long period of time in 2015.

So there is many unknown elements.

1. When the new gen will be available ?
2. Will it be affordable ?
3. massive difficulty increase or slow increase or even decrease ?
4. The Bitcoin price

Bottom line, just make sure you don't loose your house if everything goes bad. Gamble what you can afford to loose

Hope it helps

If your order direct from bitmaintech  they have 100 dollar coupons.


I could send you a few coupons. 'free'


Do not listen to naysayers if you want to mine do it.

[mettalmag]

I cant understand why DHL gives me 2200$ for shipping and fedex only 1400$.
Thank you all for your advice and opinion, today I'm going to explore the place were all these stuff will be placed. Company that is providing energy told us that they will give us 25kwt power, I think that would be enough for miners only and the air conditioner will work from another line. Im hoping to get ROI in about 10 month.

thank you so much
I wonder how does the coupon system works? Can I use several coupons in one order or just one per order?

DHL is highly location specific on if it's good for you.   I'm on the edge of a route... they put it in regular US mail vs delivering it to me.  So it adds multiple day's.  I really hate them as a shipping company.  Above is normal if he is running low on amount delivered he calls people and says he will be in X parking lot for certain amount of time and you can come pick it up.  So he get's lots of credit for delivery ... yet people drive to him.  He's pretty skummy.

I would also look at cooling again using AC is pretty uncommon at this point with mining gear.  Just is really expensive vs other options.  Normally at this point it's evaporation cooling, or high CFM's pushing heat and exhausting it.  So I would check on that part.

1 coupon per s-7    

 so

1 s-7 you get to use 100 off
2 s-7 you get to use 200 off
3 s-7  you get to use 300 off.

If you decide to order  pm me I would send you 3 or 4 free coupons and show you how to place order so that you get to use all the coupons.

I have only used UPS for my orders from bitmaintech  

 I get it shipped direct from China to New Jersey, USA

In my area UPS is better then fedex or dhl for overseas shipping.

It varies in the USA from state to state.

Pricing is:

 FEDEX best
 UPS    second place
 DHL     third place

but   with bitmaintech UPS is over 5% more and gives better service.

If you are USA  don't do one order   when orders get really big like 3 k or more sometimes issues of more fees happen.

If you are USA I would place an order for 4 using ups and four of my 'free' coupons.  pay with btc  .

wait about 6 hours place a second order  for 4 using ups and four of my 'free' coupons pay with btc.

do this again  order four and use four of my 'free' coupons  

this would be 12 machines about 6k in orders.

I am not sure if you need psus.
you get them from bitmaintech if you do. order 12  use ups  order separate  cost will be 1883 for the 12 with the shipping

at this point you  will have 12 s-7's and 12 psus.   all ordered on same day  with the 12 coupons I send you   your net would be

about 7800.

12 miners 12 psus'



I sent a pm with details on how to order with multiple coupons and money wire.

Note do not fuck the order up as you will lose the coupons.  (I have been there and  done that)

price update 0.06$ per kwh. I think it's the best price I can get in Georgia (not US).
And the last thing before I start, I need to know everyrisk factor out there. Like halving, bitcoin price itself, new chips etc.

[Amph]

i would not do it now, i would wait for the next asic generation they should come soon to face the halving, you would have a better idea on what is good to do by then

but i would suggest to not buy them used, because those who buy them new will sell them fast at higher price, because of the demand of a new asic, it's a trick used already

shipping rates in my country are so high that selling new devices abroad are impossible. Plus there is no demand of mining equipment in local market. Considering all risk factors atm I'm thinking to buy 5 S7s now and wait for new chips and get them as soon as they will be avaliable on the market, what do you think?

I can't understand one thing about halving, I was mining on the slushs pool from the beginning when the interface of the webpage was like ordinary forum one, what will happen after halving ? For example If I was mining with power of 4Ths 0.4BTC a month after halving it will be 0.2BTC not including difficulty factor ?

That's correct, your reward per block found will drop from 25 BTC plus transaction fees to 12.5 BTC plus transaction fees per block. No-one can predict what the difficulty will do post-halving, and with a larger *percentage* of a found block being transaction fees how exactly it will all work out.

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.

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

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

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
