I'm developing projects in South Africa and Senegal at the moment. Africa's a great and untapped region.

You are welcome to get in touch if you want to compare notes.

I can't message you with my contact information as you have PM's from newbie's disabled and I'm not very active on here.

Either way, I'm sure you'll succeed and there is no shortage of information and friendly people here to offer advice.

If your energy rates are similar to the ones I've seen in Africa, most concerns discussed can be mitigated by throwing money at it. The critical factor is that you are familiar with business in the region and it sounds like you are.

Throw me a PM with some contact details if you'd like to talk.

Coolant a hydrophobic inert silicone, kinematic viscosity of 5-200 mm

Not that I understand what that means.

There are some big company out there discouraging people to enter in mining because they don't want to difficulty increase. So I'm agree with OP.
Look at the Developers on FPGA they don't tell which coin and which bitstream you should use in order to make a good profit with FPGA and I heard there are company that making large amount of profit with FPGA which no one giving leak about this.
I don't know if its true but some youtuber that they have contact from some private company who develop FPGA for mining.

If you are just go in GPU the other comments here is true because here in my country mining is not profitable if you don't have free electricity source.

FPGA mining like Hashaltcoin?

Re: Bitmain Is Now Mining (BTM), over 50% of hashrate, new undisclosed ASIC
by

Bitmain Antminer B7, 96 KH/s ASIC, they currently sell it only on their Chinese website... after probably "testing" the new devices for a while in their farms.
Yeah, they are "testing" their hardwares to get as much profit as possible and when they mine enough for them, then announce that they are releasing these asic miners, already tested (in reality very used). It is their politics and everyone knows it well.
But OP, as I see, according to https://miningpoolstats.stream/bytom <-- F2pool has over 50% hashrate, not Bitmain. Currently Bitmain (antpool) shares 23.3 % of Bytom network hashrate.

Thank you for the link, Bitmain state (5th March) they operate at 90MH/s
https://blog.bitmain.com/en/hashrate-disclosure/

I also find conflicting reports for BTM hashrate, the link you kindly provided states that network hashrate is 88MH/s.

This site here reports latest hashrate for BTM to be almost double that at 164MH/s.
https://crypt0.zone/calculator/details/BTM

Always struggling to know which data to trust...

Thank you, I hadn't seen the B7. You're almost certainly correct!

I'm certain Bitmain still make their money from pre-mining undisclosed ASICs, but, this was not accounted for in their IPO documents.

Example; bitmain mining Tensority, without having disclosed any asic able to do so?

https://bitcointalk.org/index.php?topic=5117949.0

On the SHA256 front, Bitmain are currently mining at 1,692,350 TH/s.

That is as of March 5th, down from:
February - 1,790,000 TH/s
January - 1,899,700 TH/s
November - 2,339,210 TH/s

No idea of the make-up S9/S11/S15/S17.

The dropping hashrate suggests alot of their machines are selling.

In January they were running 4,788,300 MH/s of Ethereum ASICs and today are running only 154,520 MH/s, suggesting they are selling hardware through mediums other than their website.

Someone pointed out the B7 to me that is for sale on the Chinese website: https://www.asicminervalue.com/miners/bitmain/antminer-b7-96kh

This must be their new miner I was looking for.

Bitmain Is Now Mining (BTM), over 50% of hashrate, new undisclosed ASIC

I keep a close eye on Bitmain's hashrates and I had noticed a new algo pop up.

This is Tensority, which I believe is the Algo for BTM. They are currently running at 0.09GH/s which if I'm correct is approximately 55% of the coin's total hashrate.

Bitmain disclosed on the 5th of March 2019 that their hashrates on that date are as follows:

SHA256            ETHASH             CRYPTONIGHT      SCRYPT           BLAKE256      TENSORITY
1692.35PH/s   154.52GH/s      1864.75MH/s    1686.93GH/s   69.03PH/s       0.09GH/s

I was interested as I'd heard Bitmain mention nothing of these ASICS, nor have I seen a tensority ASIC from another manufacturer.

I also am surprised that Bitmain is running over half of the hashrate themselves and that they have chosen this Algo.

https://crypt0.zone/calculator/details/BTM
https://crypt0.zone/coins/tensority

I'd estimate they are making almost $300,000 per month mining BTM.

Have I missed anything here?

Hello. The S9 began to disconnect from the pool after 1-2 hours of operation. The S9 itself works. What can be wrong?

Have you tried connecting to other pools to see if you get similar issues?

After that try a different router (often home broadband routers block mining), or connecting via a different network to see if you still have the same issue.
