What's the most trusted beginner-friendly mining advice site for estimating hobby-scale profitability accurately?

There isn’t a single “most trusted” site for hobby-scale mining profitability, because accuracy depends heavily on your electricity price, hardware, pool fees, uptime, and coin price volatility. But for a beginner-friendly, widely trusted starting point, I’d suggest:

Best overall: WhatToMine

https://whattomine.com/

Why it’s trusted:

• Very widely used in the mining community
• Easy to compare coins and algorithms
• Lets you enter your hashrate, power draw, and electricity cost
• Good for quick hobby-scale profitability estimates

What to keep in mind:

• It’s only as accurate as the inputs you provide
• Real-world results often differ because of:
  • fluctuating difficulty
  • pool luck/fees
  • hardware inefficiency
  • stale shares and downtime
  • price changes

Also useful

• CoinWarz — beginner-friendly profitability calculators
• NiceHash profitability calculator — useful if you’re considering renting hashpower or selling hashrate instead of mining a coin directly
• ASIC Miner Value — best if you’re using ASICs rather than GPUs

Best practice for accuracy

For hobby-scale mining, the most reliable approach is:

1. Use WhatToMine or ASIC Miner Value
2. Enter your actual wattage at the wall
3. Use your real electricity rate
4. Subtract:
   • pool fees
   • expected cooling costs
   • hardware depreciation

If you want, I can also recommend the best site specifically for GPU mining, ASIC mining, or Bitcoin-only hobby mining.
