But on 10/13/19 the Bitmain site had a mess of stuff for pre-order or direct purchase.
Well, I think I know why Bitmain is dumping product now in mass. From the following link seems they are looking at 5nm in early 2020 and are working on 3nm chips as we speak. See this article:
https://www.livebitcoinnews.com/bitmain-ceo-bullish-behavior-unlikely-following-may-2020-btc-halving/We are utterly screwed as small miners unless the price rises significantly before these 5nm and 3nm chips are in play. Again, IMHO, why Bitmain is dumping ASIC's in mass.
I'll post 3 of the large units as examples of what they offer for prices and watts and what they would make in the USA at 10c kWh. WITHOUT the USA Tariff and Import Fees (27.6%) and shipping price from China. So I will do my calculations (again without tariff/import fees/shipping) at 10c kWh.
For these two pre-order units at least. As long as I did the calculations anyway, I'll post my links to calculators and results here.
Note: There are other units on the Bitmain site that I've not listed. Some I would have but Bitmain lists no watts for some of these units.
Also only did the below high-end units. The result is dismal enough, IMHO, no need to beat a dead horse and list all units. You'll get the idea.
I used the below link to determine hash/power/profit.
What to Mine Site. BTC Checked Box. Also, the price was taken from
https://coinmarketcap.com/ for BTC.
https://whattomine.com/asic -------------------
Antminer S17+ 73TH at 2920 watts and the price of $2,833.00 pre-order. Delivery December 1st-10th, 2019. PRE-ORDER.
-------------------
At the current BTC price of $8,430.00 at 10c kWh. You would make at flat difficulty (now) and price (today) of $5.00 per day profit. With an ROI of 566 days! Yech!
--------------------
Antminer T17+ 64TH at 3200 watts and the price of $1,802.00 pre-order. Delivery December 1st-10th, 2019. PRE-ORDER.
--------------------
At the current BTC price of $8,430.00 at 10c kWh. You would make at flat difficulty (now) and price (today) of $2.84 per day profit. With an ROI of 635 days! Yech!
----------------------
Antminer S17 Pro 50TH at (using middle watts at the low figure of the high scale) of 2250 watts. Price is $2,502. Delivery October 21st-31st, 2019. AVAILABLE NOW.
----------------------
At the current BTC price of $8,430.00 at 10c kWh. You would make at flat difficulty (now) and price (today) of $2.84 per day profit. With an ROI of 881 days! Yech!
Also as you can see from the above, this is very, very, unlikely for anyone in the USA, in particular, to get an ASIC miner at the USA average price of 10c kWh, even if NO tariff/import fees/shipping. This is also my electric rate, so hopefully, you can beat this by a considerable margin and laugh at my expense!
So anyway, IMHO, we have all seen this game before. Bitmain dumping equipment in mass just before Christmas. Takes pre-orders that are not shipped around Christmas and then because of Chinese New Year the stuff you pre-ordered that will supposedly arrive end of December 2019, will actually arrive middle of February 2010, due to all the holidays. At that point, they will be distributing newer units sometime in the spring, maybe, 5nm ASIC chip units to themselves driving up hash rate for 3-5 months before releasing to the public at inflated prices as seems to be their strategy. After say, that dump end of Summer, they then have the 3nm stuff to put in play for equipment again at their data halls first. Thus the 'long-con' IMHO (see article) of buying miners now because it is going to mature slowly theme. Hey, trust us.
Indeed it is the usual scam of rinse/wash/repeat.
The ONLY way anyone could mine these days, under these conditions, again, IMHO, is IF you are mining like heck at a loss and to HODL for fun on the expectation of BTC doubling or some such after halving in 2020 or some other long term dream. But in reality, if you believe such, you'd be better off with an automatic bank withdrawal monthly buy off BTC to HODL on an exchange until that point happens someday as your bet, of BTC doubling in price.
Looks unlikely I'll be mining anything of any note until maybe 'used' equipment in 2021 at this rate.
Anyway, fun while it lasted.
later
