Hi, maybe its a problem with the pools?
I have mine on nicehash right now and I am getting this:
Nicehash shows 98000 Sol/s. That seems fine.
Graph on nicehash looks like this:
I am wondering why the A9 shows this strange curve. Like the hashrate drops for some time. But why?
Profit on nicehash seems to be nearly as estimated.
Ideas?
What you have in hashrate report, I got on Nicehash 23% rejected orders. So from 50 kH/s, nicehash confirmed only 33-38 kH/s, rest - rejected...
I have 0.50% rejected. Seems fine.
All seems fine, except the reported speed from the miner.
Question: did you using 100 Mbits ot 1 Gbits network switch for miners?
Its a gigabit port on the switch, but connected via Wifi and internet connection is a slow one.
I dont think its my internet.
Can you post what your graphs look like?
Zcash Flypool..
37.2 KH/s 1394 (76%) 451 (24%) 8 minutes ago
37.0 KH/s 1386 (75%) 456 (25%) 8 minutes ago
Now I had 13% rejects on Nicehash. I rebooted and it went down to 1%.
So what is considered as 'Good Deal' for this device. I mean if you buy this at $10,000 and it makes you $80 per day, its still $2400 a month and payback period could be down to 4 months, but we all know that's not realistic as difficulty goes up and profit per day goes down. So at what price this seems like a safe bet and can be considered as a good investment, considering every factor. I am thinking $6000 purchase price seems pretty good if it can be delivered in a day or two.
You have to decide that. You get 2 units for 10k$. If you plan to mine and hold, you may increase or decrease your profit. If you just want to ROI fast, you have to consider how many ASICs hit the network. Nobody knows that, its guess. Also you have to consider forks. If Zcash etc. dont fork, at least for the next months, profit will be good.
I would not buy an ASIC and take profits or ROI as given depending on todays facts. I would only invest part of my profits and consider it as a risky investment.
See, worst case: You buy one, it breaks after some days, you send it to warranty, it takes weeks to return, you miss the high profit phase.
In general: First batch adopters have a reasonable chance to get ROI if they get their units fast. 2nd batches seem to be fine also. But every overpriced 3rd and higher batch ASIC, especially if other companies also flood the market, is a bad idea.
Examples: Baikal BK-X for 1600$: They hope customers believe in ultra profits with non specified "more algorithms" that shall come somewhen. ROI is like 400 days right now.
Bitmain: Every miner they sell at the moment - although the Z9 for August might be a buy if you have a 300$ coupon. Consider forks though...
