Been using what to mine for a while now, and honestly it's one of those tools that just makes sense if you're serious about mining profitability. You throw in your hardware specs—hash rate, power draw, all that—and it gives you real-time data on what actually pays out across different coins and algorithms. That's the core value prop right there.

What makes it stand out compared to something like NiceHash or Minerstat is the depth of customization. You can adjust electricity costs down to the exact rate you're paying, factor in pool fees, choose different price sources. The dual-mining feature is solid too if you're into that. Historical reward charts help you spot trends, and they've got web widgets if you want to embed live data somewhere.

The learning curve is steeper than some alternatives, not gonna lie. If you're just getting into mining and want something dead simple, what to mine might feel overwhelming at first. But once you get past that initial setup, the tool becomes incredibly useful for actually making informed decisions about which coins are worth your electricity costs.

What I appreciate most is that it's free, no account needed, and the coin coverage is genuinely comprehensive. You're not limited to just the top 10 or 20—there's real depth there. For anyone trying to figure out what to mine and optimize their setup, it's pretty much essential. The community trusts it for a reason.
