Hey all,

I have been mining for some time now with two antminer s7s and one antminer s5,  hashrate totalling at a little over 10Th/s. With that hashrate I am able to generate approximately $100(0.025btc) per week given the price of 1 btc remains over $4000.

Not forgetting to mention that I am not paying any money for electricity due to the location of these miners.

I am interested in upscaling my mining operation with a start up capital of $5000.

What equipment would you recommend?

I have been thinking of continuing with antminer s7's due to the availability of them and their low cost.  I belive that about three s7's will give you the hashrate of one s9 however the power consumption is triple,  however,  power consumption isn't a worry for now.  Secondly one antminer s9 is currently being sold in the range of 2500$ -  3500$, where as one s7 would be about $700.

Let me know your thoughts on this.

Thanks

Well, if electricity isn't a concern for you, go for the most cost effective hash rate in terms of HS/price, that way you'll be able to scale more and have more profits. s7 seems like a good deal in this case.

is these days a S7 still profitable at all?

The s7 is still profitable based on how much you pay for electricity

Yes this is exactly what I'm thinking hash/price,  the S7 wins hands down.

Wish I could find good s7 miners for under 600 tho.

or maybe is it possible to get it cheaper?

have you seen the amazing money returns of a L3+ and D3 miner of Bitmain?
5.000US$ a month in earnings
how is that even possible?
if you are looking to invest your money the safe in a money macking machine theres no other place than here
ive been looking to invest in the crypto market
 thanks god its a bit cheaper now to invest in Altcoins
i want to buy my first asic miners looking to invest some good amount of my savings
I found some L3+ and D3 at https://www.storeantminer.com/product/bitmain-antminer-d3-used they are in stock
and im looking forward to buy there
as they have good prices

I would consider an avalon 6 used

or an s-7 used

Wow,  I'm liking those prices already. How reliable is this website tho?

They are the USA distributor for Canaan.io

Go to the canaan.io website to see what I mean.

And you can pay with paypal. I grabbed an Avalon 741 before they sold out.

I paid with paypal


Forgot Canaan.io builds the Avalon gear

Kool,  I'll check them out

Just buy antminer d3 and sell the hashing power to the nicehash, it would give you a nitcoins and its much more then just to mine a bitcoin, also d3 has a much better roi!

your advice could back fire  big time.

it may not roi faster then a s-7 using free power

D3 at this point is a BAD option - profitability is going to be very poor by the time the CURRENT batch actually ships and ROI is almost definitely going to be quite a bit worse than the S9 would be by then.

 I'd go with the S7 or Avalon units, depending on HOW MUCH free power is available.

Figured that much.

I am also saving up to invest in a solar array as a backup (or second location) for my miners.

I too believe that Antminers S7/S9 or Avalon miners are the way to go for now.
