Antminer S21: Bitmain's New Challenger in Bitcoin Mining

In the fast-changing crypto scene, Bitmain is grabbing attention again with their new Bitcoin miner, the Antminer S21. The community is buzzing with anticipation as they wait for more details, and there are hints that this machine will feature some major advancements in mining efficiency and power. What We Know About Antminer S21 Bitmain has put out a teaser video that’s got everyone excited. Rumor has it that the Antminer S21 can mine at an incredible 200 terahash while only pulling about 3,000 Watts. The coolest news? It looks like Bitmain is about to unveil a groundbreaking Asic chip, potentially achieving a jaw-dropping efficiency of 15 joules per terahash. Current Bitcoin Situation As of August 21, 2023, Bitcoin's price is sitting at $27,400, which is a bit of a drop. The crypto market is full of ups and downs; remember Bitcoin hit an all-time high of $68,789.63 back on November 10, 2021. Everyone's curious about when the next big Bitcoin Bull Run will kick off and what the new record might be. The Competition During Mining Disrupt 2023 in Miami, Zeely Miners rolled out their K-10 Ultra Bitcoin miners. These air-cooled machines crush it with over 200 terahash while using just over 4,000 Watts. With competitors like these in the mix, Bitmain’s release of the Antminer S21 feels pretty well-timed. Profit Predictions Looking at the rumored specs, the Antminer S21 could make about $13.39 in Bitcoin each day. If we factor in electricity costs at around $7.56, that leaves a profit of about $5.83. Keep in mind, these numbers are based on Bitcoin's current price and can change with market shifts.

15 watts would be big real big

Absolutely! A power efficiency of 15 watts/TH would be a significant improvement

I was expecting more like 18 or 19. Have to order one when they come out.

In the top 7 profitable ASICs there is not a single bitcoin ASIC! https://www.asicminervalue.com/ These are the closest competitors, Bitmain Antminer S19 XP Hyd (255Th) 5350W MicroBT Whatsminer M53S (260Th/s)  6760W but if a new ASIC (400Th/s) 6000W appears, it will change the mining market. Only they need to hurry to start selling at the end of September, because halving is coming soon.

You are right  , most depends @ what price per TH/s will it be launched . Hydro miners has some slight additional cost as a radiator. There is no air cooled miner which can reach that performance released yet. I really don't care about the profitability, the most i care fastest ROI For some people with free power it would be something like S19-90ths which is only 7-8usd pet ths. S21 will be at least 20-30usd per ths.

If the Antminer S21 lives up to its rumored specs, Bitmain might just redefine efficiency standards

I have seen 2800usd for a 136th s19xp a 210 th unit burning the same 3100 watts means  74th for the same power. or $4.50 a day extra so in 1000 days it earns 4500 usd more than a 136th s19xp 2800+4500 = 7300 usd my guess is : 7500 usd to 9500 usd for 1 unit preorder and at least a 2 month wait.

The K-10 Ultra miners old version been said in conference are priced 25usd per ths , the new version 200mhs @4000w is priced 30usd per ths. Keep in mind the prices will change depending on market conditions as these machines manufacturing cost are dirt cheap. If profit increases they will charge lot more for TH/s

I'm betting on ~18.5/TH

I'm not a Hydro ASIC, but I have experience with Hydro cooling on a PC. Hydro cooling is more efficient, but any non-factory solution requires great care in installation and use, because the principle is the same. And the repair of such equipment is more expensive. If we discuss free electricity, then I don’t think that anyone has large limits for free electricity, not 1-5 kilowatts per hour, but 20-50 kilowatts per hour.

Yeah shouldn't be far of that.

you think they will sell this for 18.5 x 210 = $3885 usd seems too cheap

I mean the watts per TH/s, price will be around 25-30usd per th/s i assume.

I would tackle it from a different perspective. With a daily production of 210T, you can earn approximately 0.00046200 at the current difficulty level. As a result, the break-even price would be $13,680. However, the S19XP's break-even price is higher at $21,080. If Bitcoin were to drop back into the $20,000 range, your profitability would be compromised, but the S21 would remain a profitable option.

Yes, now on the official website of antminer S21, taking into account the discount, it is offered for $5,800(~$27.62 per TH/s) the full cost of $6,300 ($30 per TH/s), with delivery in April 2024. Power efficiency according to their statement is really 15 ± 5% J/TH. https://www.antminertech.com/shop/antminer-s21-bitcoin-miner-210th-for-bitcoin-mining/

That site looks like a scam. like look at the image in detail. you cant tell what anything is and it looks AI generated

If it looks like a scam, swims like a scam, and quacks like a scam, then it probably is a scam!

yeah that photo looks like it has water 💧 cooling ports it is a fake.

Canaan Technology, a China-based manufacturer of cryptocurrency mining machines, has launched its new liquid-cooled mining machine A1466I in Singapore. The machine has a hash rate of 170 T and an impressive energy efficiency ratio of 19.5 J/T, making it Canaan’s most efficient machine to date. The A1466I also boasts a price tag of less than $18.88/T, making it an affordable option for miners looking to maximize their profits. This launch marks a significant milestone for Canaan, as it is the company’s first machine with an energy efficiency ratio under 20 J/T. https://cryptorank.io/news/feed/aeda9-canaan-launches-new-liquid-cooled-mining-machine-in-singapore This is not the best energy efficiency on the market, but maybe the company will offer a better price to compete.
