Topic: Need Advice - Trying so hard to build a profitable farm (Read 1485 times)

Why create a thread if you won't come back and reply.

As others have said, for $5,000 you are not going to get 100TH/s without a huge electricity bill, unless you have free power, but you may have a lot of questions to answer depending on where you are located.

I've been playing around with various miners for a while now, going way back to mining Litecoin with CPU and crappy GPUs beginning in late 2011/early 2012.

I've been piecing into my current multi-currency mining farm over the last 7 months or so and have:

• a single MSI r7 370 Gaming 4G GPU which is mining ZEC, but had been mining ETH until a few weeks ago.
• a GekkoScience Compac USB stick miner mining for Bitcoin (17.8± MH/s solo mining on solo.ckpool.org)
• a Bitmain S7LN miner that has been modded by sidehack to use a lower voltage and clock to make it more efficient (currently getting 2.0± TH/s).

My next equipment purchase is likely to be a couple of Canaan Avalon A721 miners. These miners will be part of a group buy and hosted in Canada. These miners get ~6TH/s and use 900 watts of power.

If I had $5,000 to spend now, I'd probably go for 4 or 5 (depends on the group buy price) Canaan Avalon A721s plus one controller in the group buy, and pay to rent the power supplies. I'd also then start rolling the profits back into purchasing more Avalons until the Next Big Thing™ rolls around. Another viable possibility is to buy 4 or 5 GPU rigs (depends on prices of GPUs) and mine either ETH or ZEC.

Even though they have higher hash rates and are more efficient from a GH/watt perspective I'm avoiding the Bitmain S9 miners based on the reported build quality/reliability issues and the challenges of having warranty repairs made. If Bitmain cleans up their manufacturing and addresses the reliability/warranty repair concerns, I'll consider buying from them.

Additionally I will be purchasing some of the new GekkoScience devices when they become available.

Cheers,

100TH is 8x Antminer S9s (in most batches) - or well under *3* x $5000 even with power supplies and some left over to set up an acceptable cooling system.


 Sometimes you just have to build up to a goal - take your mining profits and roll them back into expansion.

Sadly it's not the right time now to appear on market with low budget as a mining farm. You need not one 5000 but 10x 5000 will be enough for your goal, remember that you need good cooling system for your miners.
What will be innovation today? If you appear on market with your better miners, miners wich uses low energy and has many th/s. With this, your name will be popular in some days.

forget about it!
adaseb gave the reasoning behind it-you can get gear to total to 10th
you will pay 5 times more for electricity as the gear will be less power efficient,thus making ROI impossible
if your power is free than you can buy the most efficient cost/gh+overclock
if your power is dirt cheap then you will have to factor gh/Kwh efficiency in
to sum it up:10k $ is not enough to start bitcoin mining,look at mining altcoins with GPU rigs instead
even though it is marginally profitable as well

Yeah you can probably find a bunch of S3's for $25, OC them to 500GHs, buy 200 of them and you will get 100TH/s

$25*200=$5000

Every month you will make $2000, BLING BLING!

You will need close to 100,000Watts of electricity however.

First off, make sure you have free electricity, because with such a constrained budget you won't make anything even with 100TH/S- it'll mostly be outdated, secondhand, and last generation gear anyways. Stock up on BFL 600+ ghash miners you can find for cheap, S7s, and Spondoolies-Tech racks. S5s will not be nearly as viable as they don't provide as much $/GH.

Well with $5000 you can probably buy a bunch of S1,S2,S3,S4, KNC Jupiters,etc and it might add up to 100TH/s.

You will need FREE (not cheap) electricity however.

(1) Don't expect ROI of less than a year. The market hasn't supported THAT for a while (unless you got VERY lucky as an early ZEC adopter or a fairly early ETH adopter or a VERY early X11 ASIC adopter).

 (2) Location location location. Locate somewhere with VERY VERY low electric cost if you except to have a chance at long term profitability.

 (3) Live with the fact you're late to market, there is NOTHING you can do about that (unless another new coin shows up that managed to turn into another ETH or at least another ZEC).

 (4) X11 / X13 / X14 / X15 / QUARK / Qubit like SHA256 and Scrypt before them are dead for GPU mining, the Baikal ASIC mines ALL of those.

I've been working long hours just to save up enough money for a farm, but even with 5000$ it's not enough to get enough equipment to meet my 100TH/s goal. Even if I do meet that goal it seems like my ROI wouldn't be for a year.

What other options are still profitable? should I build a quark algo miner rather than try to get a bunch of ASCIs?

What can I do to not be late into the market??
