I’m not planning to mine any altcoins. Strictly focusing on Bitcoin long-term. I want to pick a miner that’s optimized specifically for BTC and will stay viable for at least the next couple of years. What’s the best choice for a no-compromise Bitcoin-only setup?

If you're committed to BTC and want something purpose-built, I’d strongly recommend going with the best SHA-256 miner https://scalar.usc.edu...ty-/index?t=1748507914228 available right now. Unlike multi-algorithm machines, SHA-256-focused ASICs are fine-tuned for maximum performance and efficiency specifically on the Bitcoin network. The top units this year are pushing up to 280 TH/s with sub-30 J/TH power efficiency, which means you’ll be getting solid performance while keeping electricity costs under control. The hardware is also more stable — fewer fan failures, better cooling duct design, and heat-resistant components that last longer under continuous load. I’ve been running one of these new models in my garage for four months, and it hasn’t throttled or glitched once. Setup was seamless, and remote management tools are way better than they used to be — real-time tracking, auto-restart, firmware update notifications, the works. If you’re building a BTC-only operation, go with a miner built from the ground up for SHA-256. The performance difference over time is night and day compared to older or hybrid models.
