Update for the delivery of the Bitmain Antminer L7

Where’s the Bitmain Antminer L7?

Many pre-orderers are currently wondering where the Antminer L7 they have ordered is.
The Bitmain Antminer L7 with 9.5GH or 9.16GH each was offered via Bitmain for November and December batches.
Not a single copy has been delivered worldwide (as of: 03/01/2022).
There is still no final information on the delivery of the L7 from Bitmain.

We investigated this question and found surprising information about the whereabouts of the L7:

But let’s start at the beginning:
Why was and is there a delay in the delivery of the miner? Pre-orderers who inquire directly at Bitmain currently all receive the same answer.
Due to the global semiconductor and chip shortage, Bitmain does not receive the desired amount of chips to produce the miners on time. Then there is the conflict with China. After the Chinese government banned the mining of cryptocurrency, Bitmain suspended the sale of the miners for the time being and planned to relocate its factories from Shenzhen (China) to Malaysia.

But are these really the only reasons for the miner’s delay?

Bitmain has had late deliveries in the past, which were not necessarily related to the lack of chips.
So the Antminer T19, which was announced for June 2020, has been postponed by 3 months.
The reason for this was an internal dispute and power struggle between the two CEOs of Bitmain (Jihan Wu and Micree Zhan), who have been arguing since 2019 about who is the sole managing director of Bitmain.
After Jihan Wu was forced to give up his post, he retaliated and attempted a coup by stabbing the branch with guards while Zhan was on a business trip.
Both managing directors caused such violent unrest in the company that even the employees no longer knew who the managing director was.
As a result, not only did one of the largest IPOs (Bitmain) in China burst, but Bitmain lost some of its goodwill, trust and, above all, seriousness.
But Bitmain (2018) also developed an ASIC miner for Monero (X3) in the past, which at the time was much more effective than GPUs and CPUs at the time.

Through a reader we were able to find a surprising post on Reddit by a user (Straight_Media3392):

In the post, the user describes the following:
If you look at the chart on the pool provider LITECOINPOOL, you will find a user named “andyputra” who has a total hashrate (alltime) of 69289566000 GH at a current hash speed of 8578GH / s (equivalent to approx. 902 Bitmain L7 9.5GHs).

Using the formula:

Total Hash = Speed ​​x Time or Total Hash: Speed

The following results:
Time = 69289566000: 8578 = 8 077 589 sec.
8 077 589 sec = 93 days

In other words, the total hashrate was mined within 93 days. If the user “andyputra” is actually BITMAIN, it can be assumed that the miners are currently operated by Bitmain in order to generate profits.
Should this actually be Bitmain, this shows again that Bitmain has hardly learned despite the past and continues to make profit at the expense of its customers.

To draw a conclusion at this point:
If this is actually BITMAIN, it must be said that in view of the past events this is a serious breach of trust. But there is hope because Bitmain doesn’t seem to understand one thing!
In the past there was hardly any competition for Bitmain, as there were hardly any other ASIC miner manufacturers.

But in the meantime manufacturers such as Goldshell, Canaan and IBELINK have established themselves (also owe Bitmain) and are very reliable with pre-orders such as the KD5 and the recently released CK6.
In conclusion, the question remains how Bitmain customers will react to this misconduct in the future.

BITMAIN Antminer S19XP 140TH – Bitmain releases the most powerful Bitcoin ASIC miner ever produced!

At this year’s World Digital Mining Summit 2021 in Dubai, Bitmain, the world’s largest manufacturer of ASIC miners, published the most powerful Bitcoin ASIC miner in the world.
The BITMAIN ANTMINER S19XP has a computing power of 140TH / s and with 21.5 joules per terahash is far more efficient than all previous miners.

In all probability, the first miners will be delivered in the third quarter of 2022.
Since Bitmain does not publish sales figures, it is uncertain how many S19XPs will be shipped at launch. China’s recent crackdown on cryptocurrency mining has forced Bitmain to relocate its factories to other countries. In addition, there is the global shortage of semiconductors, which will make it more difficult for miners to acquire.

In terms of price, the new BITMAIN ANTMINER S19 XP will be around 10,500 USD.

The miner is far more efficient compared to its predecessors. Despite the hashrate of 140TH / s, the new S19XP only consumes 3,010 W. This makes it (21.50W / TH) the most efficient miner in the world.
In comparison, the S19 Pro is at (29.55W / TH).

MillionMiner was there for you and was able to collect some impressions of the new miner:
