A heated debate is brewing among crypto enthusiasts over whether to invest in a used S19j Pro + for $350 or a new S19k Pro for $450, both currently non-operational. With electricity costs not a concern, users are sharing insights on Facebook Marketplace about the best choice for apartment living in 2025.

The Choices at Hand

Both models are part of Bitmain's popular S19 line known for high hash rates but come with their own set of challenges. Users are considering these miners despite their non-functional states, keen to get started with mining.

Common Concerns Among Users

  1. Noise Levels: Many users warn that both models may be loud and heat up quickly. One comment emphasizes,

    "Both models will be TOO LOUD and TOO HOT for your apartment."

  2. Power Requirements: Another critical issue is the power outlet needed for these miners. A user remarked that the S19s require a 240V outlet, stating,

    "You can't just plug them into a regular outlet."

  3. Alternative Options: Alternatives like the Canaan Avalon Q, noted for being quieter and easier to manage, are frequently recommended. One user mentioned,

    "Get the Canaan Avalon Model Q. Perfect for home mining."

Mixed Sentiments Among Buyers

While some users appear excited about the potential of the S19 series, others express hesitations. For instance, while one buyer has had a positive experience with the S19k Pro, saying, "It's awesome!" many others suggest reconsidering based on living conditions.

Curiously, the price difference of $100 does not seem to sway opinions significantly since the reliability of the S19j Pro + is often highlighted.

Key Takeaways

  • β–³ Noise is a major concern: Many fear that operating these miners in apartments could lead to complaints from neighbors.

  • β–½ Electrical requirements: Users must ensure suitable outlets are available for these powerful devices.

  • β€» "The S19J Pro is one of the best miners Bitmain has made." - User insight

As the mining community gears up for the year, the decision for many hinges on balancing cost, functionality, and their unique living situations. Time will tell which model proves to be the more valuable investment.

Future Mining Landscape

Experts predict that with the rising interest in cryptocurrency, the S19 line could see increased demand throughout 2025. There’s a strong chance that as more people try home mining, awareness on noise and power requirements will lead to a surge in alternative options, like the Canaan Avalon Q. Some estimates suggest that nearly 40% of potential miners will lean toward quieter models for their homes, especially in urban settings. As the community shares more insights online, potential buyers will benefit from a more informed decision-making process about what to purchase.

A History of Unexpected Choices

Looking back at the laptop boom of the early 2000s illustrates a fresh parallel to the current miner debate. Many consumers flocked to purchase bulky models without considering their portability or noise, driven by excitement over new capabilities. Just as those early adopters later influenced the shift toward lightweight and quieter designs, today's mining enthusiasts may reshape the market towards efficient and less intrusive models. This progression serves as a reminder that initial popularity often shifts priorities, propelling a new wave of standards in technology.
