Bitcoin Asic Antminer S21 200T 3500W – SHA-256
Antminer S21 is an innovative Bitcoin mining device developed by the company Bitmain. In cooperation with TSMC, a leading semiconductor manufacturer, it plans Bitmain introduce the S21 series with advanced 5nm chips, increasing efficiency by up to 40% compared to previous S19 models.
The market launch is expected to take place towards the end of this year, with production ramping up in 2024. The name "S21" follows an odd naming convention Bitmainu, thereby emphasizing their commitment to progress. This efficiency improvement not only increases the profitability of miners, but also addresses concerns regarding the environmental impact of mining.
Overall, the Antminer S21 represents a significant step forward in cryptocurrency mining.

First of all, thank you for your interest and support of Apexto. To avoid misunderstandings in the process of purchasing a miner, please read the following notes carefully before placing your order. Thank you very much for your understanding!
1 – Due to the specific dynamics of the miner market, it is possible that the price of the miner has changed by the time we receive your payment and we may have to return your order.
We use a batch process for all miner orders and have very limited quantities of each batch. The price of different batches of miners is different, even if it is the same model of miner. They sell very quickly. Due to the highly variable and demanding market, the price could be different every day for stock miners. So there is a possibility that the price of the miner has gone up by the time we receive your payment and we will have to refund your order.
2 – About stock miners
The delivery date of the miner in stock will be 3-7 working days. Once we receive your order, we will immediately inform our technical center to test the machine you ordered and make sure it works well. We will also send you a video for your review. We will send the machine to you after we make sure all its functions are in order. Then we hand the machine over to our carrier for shipping. We will update the tracking number on the website and you will receive an email with the details.
3 – About pre-order miners
The actual delivery date of the pre-order miner depends on the manufacturer's delivery date of the miner. We will include the estimated delivery month of the pre-order miner on the order page so you can consider your decision. However, delivery may still be delayed. If the delivery date from the manufacturer is moved, the delivery of the miner from Apexto will also be delayed. There is also the possibility that the manufacturer will not be able to produce the miner in the expected time, in which case we will process a refund for your order.
