The next era of mining

In Bitcoin mining, it’s crucial to stay ahead of the curve in terms of technology and efficiency.

With all of the external drama happening in the BSV blockchain, I am happy to take it upon myself to remind everyone that if we are all going to make it, it will be because we focused like laser beams on our own businesses and our own success.

In Bitcoin mining, it’s crucial to stay ahead of the curve in terms of technology and efficiency. My previous explorations of Bitcoin mining economics highlighted the dynamics of surviving and thriving by mining, emphasizing the need for constant adaptation and forward-thinking strategies.

Against this backdrop, the Bitmain Antminer S21 and S19 K Pro models have emerged as leading solutions for hashing partners seeking to optimize their profitability in anticipation of the next bull market in 2024-2025. These “next-generation” hashing rigs offer unparalleled efficiency, making them a prudent decision for those looking to upgrade their mining hardware while also preparing to upcycle their tiring fleet.

Are you still operating rigs that run at or below 100TH/s? Then this article is for you!

Technical superiority of S21 and S19 K Pro Antminers

The S21 and S19 K Pro Antminers from Bitmain stand out as the leaders in the current generation of efficiency achievements in SHA256 hashing technology. These models epitomize the industry’s advancements in efficiency and performance. The S21 series is currently available to some key players in the industry, and they are indeed a testament to Bitmain’s ability to keep breaking the glass ceiling on chip efficiency, boasting a formidable 200Th/s hash rate and consuming about 3500 watts. In comparison, the K Pro series also made a significant leap with its use of 5nm chips and modified S19 architecture, which has been leading the charge since the last bull market, offering a hash rate of 120Th/s while notably reducing power consumption to 2760 watts—give or take 5% at the wall.

These improvements in the S21 and S19 K Pro models over their predecessors are not just incremental but transformative. The adoption of these models is a necessity for anyone who wants to stay seriously in the game for the next one to two year cycle as global hash power continues to hit all-time highs, but overall profitability stays in a middling low area—creating some extra opportunity for BSV hashers over the BTC contingent.


Because BSV profitability is often higher than BTC, but the open market price for rigs is based on BTC-only numbers. Big benefit for the big blockers!

Overclocking, up-cycling, selling

For anyone still running older S19 models in the 100 TH/s or lower range, there are two options:

1: Time to overclock, mine in an immersion setup, or otherwise “Frankenstein” your rigs to generate more power as profitability rises.

2: Prepare them for resale when the market is at a fever pitch over profitability. Used rigs will sell for a premium when fiat prices for BTC reach new all-time highs because Bitmain will have months-long back-orders, and used hashers can be flipped to newcomers very quickly. This is the time to offload older models to newcomers who want to wet their beaks in the mining game.

Market dynamics and the case for upgrading

Rapid technological advancements and increasing mining difficulty mark the current landscape. This scenario makes the case for upgrading to more efficient mining hardware like the S21 and S19 K Pro Antminers more compelling than ever.

The advantages of these newer models are not limited to their superior technical capabilities. The economics of mining, including factors like electricity costs and the fluctuating price of Bitcoin, play a significant role in determining profitability. The enhanced efficiency of the S21 and S19 K Pro models translates to lower operational costs, which can be a decisive factor in maintaining profitability, especially in a market where margins are continually squeezed.

For hashers currently operating with older, less efficient ASIC fleets, upgrading to these newer models represents a smart strategic decision. Not only do they stand to benefit from improved efficiency and reduced costs, but they also position themselves to take full advantage of the anticipated bull market in 2024-2025. By upgrading their hardware now, hashers can ensure they are well-equipped to capitalize on favorable market conditions when they arise.
