I am loooking for some good hashing power gpu miner, can anyone suggest me any ready miner as i need to setup a small mining farm. Also anyone knows about this newly launched server miner promax7, how good is it? is it reliable? anyone ordered it?
Tbh until I got this reply, I'd kind of forgotten about GPU mining since the ASIC launches in 2013.
However, in the shadow of Bitcoin and Ethereum being driven by opportunism, people are still attempting to get in on the "ground floor" of alt coins.
I don't mine anymore, I made a handful of btc and cashed out when it was like $800, before it made half a million dollars, and sure if I had HODL, it would be a very different story helping to buy a house and a tesla p100d, sic.
I don't regret it though, I had fun.
If you get into this,
mining altcoins on something like nicehash.com switch/rotate between different alt hash networks that aren't easily converted to ASIC networks, especially scrypt variants.
Altcoins are ... a niche. As long as you get in early and fast, it will make money back. Perhaps paying off in 10 months what you invest in hardware and power consumption. Run multiple calculators online for the costs and drop the estimates by 10% each month to be practical.
You might get $3 to $15 / week for a modern GPU like the 1070 or rx580. $0.10 to $2 a day, 0.00002 BTC depending on how 'generous' the pool is when it gives you the scraps, after it has paid off 490,000 other accounts.
If you buy 12 graphics cards, and in 2020 it all falls flat, make sure that the gpu's are resellable. Have contingency. Sell current gen tech to internet cafes, etc.
Do not be optimistic about cryptocurrencies. Ever.
They are ruthlessly inefficient and you don't have the resources to get ahead unless you're going to work unethically or illegally, or can insulate yourself from people who are going to be ruthless, unethical and stupid. Or some combination of the above.
FWIW, the promax7 looks like a custom cluster with what looks like ... 34 GPU'S in a box. Which is both cool (sic) but also questionable. I don't know any of the build choices, and it might have stability issues, as clusters often do, ie having custom code linux clients you won't have support for if the company goes silent one day.
Aside from the expense of buying 10 to 20 ~$400 rx480 and rx580 systems, or blending both in the same cluster / rig. Which is actually not a bad idea for futureproofing against ASIC resistant blockchain network changes, ie requiring a bulky memory storage for every work unit , so it needs 5gb+ of VRAM to hash a block effectively, or it has to shuffle work to and from System RAM which would need to use more of the PCIE bus and expensive system RAM / 32gb SSD'S and NVRAM like devices, such as the Intel optane storage.
Altcoins are not predictable for the future. A machine that you buy might be worthless in a year, or worthless as to cost more than it produces. Even with solar power or wind generated power, hydro, whatever, just because the whole system is variable.
The downside is, altcoins are readily abused by speculators and opportunists, not investors or miners. The value could depend on the day, or the arbitrary difficulty of the hash network of the day.
What could generate $45, could be $0.12 within a week, or a day if the network itself is not ASIC resistant,
or, someone builds a power efficient GPGPU system at scale, which NVIDIA has already claimed it wants to build and sell, a general purpose GPU for encryption and well, mining altcoins will be the first practical use, along with more practical things like SSL acceleration for eStores and having thousands of secure web pages/VPN connections open at the same time.
They hope.
Anyway, do the research, find out how to build a mining rig cluster, which isn't super hard with raspberry pi 3b computers as the "boss" / executive of the network, which boots up and manages the motherboards and hands out the mining work.
You just set up the power, duct up some multi fan cooling, find/make 3d printed GPU brackets and you've saved yourself $3,000 on a 30+ GPU mining system.
