If you mine Eth, the rx 580 is close to gtx 1070 in performance. rx 570 4gb is close to gtx 1060, but some special rx 570 can perform like rx 580/gtx 1070.

Wow those prices are really crazy. Is this in USD right? If you lived closeby I'd sell you a gtx 1070 for $400. If you can get an rx 580 8gb for $300 that's decent. What about any people selling used closeby? A fair price for rx 570 4gb used should be around $200-$230. 570 8gb $250-$270. 580 8gb less than $300.

Litecoin went from high $30s maybe close to $38 to $24 which was a significant move down during that time. Thus FUD was spread. Its funny because it happened again later to roughly same values. I remember a lot of people saying July batch would not ROI let alone any batch later.

I would try to buy from Bitmain given that stock is in and out due to people reserving and not paying. If I wanted first two batches, I'd likely pay 7-8 k for batch 1 and 4-5k for batch 2, but I doubt people on ebay will sell it that low.

What is price of gtx 1070 / rx 570 4gb ?

This reminds me of the litecoin thread back in May. When prices dropped everyone was creating these estimates, pretty much same verdict that the L3+ would be unprofitable. This was followed by more evidence as the market had a correction. We all know how that turned out. Let's wait until the first two batches ship before discussing more. At the end of the day just risk what you are willing to risk, but do not throw your life savings away.  

Do not buy this. If those cards die you're out of luck. Stick to buying gtx 1060 or rx 570 if you can buy cheaply. How much is a gtx 1060 3gb where you live?

Bitmain doesn't need to offload any weight. They have made a huge amount on selling the equipment on these and holding coins. I think they are want to reduce risk in holding btc/ltc so they are wanting to sell for USD or lower their risk.But they know they can survive for a long time. Maybe they want to outcompete others but Jihan is no fool. He would not sell equipment to ruin people intentionally. Otherwise this would be bad for his precious bitcoin.

I think the only batches you should buy are the first two. Last few do not pay more than $4000 on ebay. Also I remember the same FUD about when the Antminer L3+ was released. Everyone was saying the same stuff, right after hashnest had released 3000+. It turned out the price of litecoin rose so well that all the miners made 500% ROI atleast.

I heard there will be a delay for later batches, and they are mostly getting money before other competitors start releasing. Is this true?

I would also say do not buy these. Better to spend money on their ASIC equipment or build your own gpu rig.

I'm such a loser . I purchased some equipment in June that has made back 60% of the cost oh the suffering. People actually paid $700 for gtx 1070 lol?

Yeah that's what I'm saying, but it started at 30k, but people could hold a lot of purchases and not pay, hence who really knows how many were bought. I personally was testing it and the number drops despite not paying for any.

Everyone is speculating about this huge november batch because of this 30,000 sold number. I remember buying and not paying and it took away from that number, so who really knows how much were released. 20,000 is quite a bit to sell though isn't it?

Here is my wild estimate / speculation on batch size:
Batch 1 early September: 2000
Batch 2 late September: 1000
Batch 2: 3000
Batch 3: 5000
Batch 4: >5000

Updated, now selling 3 November batch. Was going to keep, but increasing power would require too much money.

I like how everyone expects to get $10000 in 2 months by buying a $2500 miner. It looks like October is a great batch considering Bitmain and everyone else will be testing September and profits will drop. Might as well buy $1000 less right?

Updated: T4T all!

If Bitmain is doing like before, this number is way to high. It's probably mixed with people that just buy and take out the count but don't pay with coin. In the previous batches, I would make really late purchases and leave them open expecting the "Sold Out" to come back, but they never did. It may just be extras to prevent people buying 50 and not paying at a time.

Think about it this way. Let's assume the hashrate does spike something very high. Would you rather buy 2 Antminers for $3k and match the Dashmaster that costs $10k. Sure the Dashmaster may be delivered earlier, but at the same time, the hashrate may not be what they post. Plus the Dashmaster has to compete with Antminers being released in october and sept, so it's not like they reach their profitability either. Also, the Dashmaster might be a 22gh/s with the wattage, who knows. I don't think it's reasonable to expect the miner to itself off within 1 month. That's just too much to ask for.

I think the reason to go gpu mining is that it is less risky than investing directly if you don't watch the coin values constantly. Also, people like the fact that they can buy hardware and eventually have it free to mine anything. The cons of course is slower path to riches and it takes effort to monitor and you would have to know how to fix things when they occur.
