7. What's a mining pool?
A group of miners combining their computational power to earn more consistent rewards.
8. What is a bitcoin mining calculator?
A tool that estimates profitability based on your hash rate, power cost, and BTC price.
9. Can I mine bitcoins for free?
No. Even if using free apps, there's a cost for electricity and hardware usage.
10. Are there mobile apps for mining?
Yes, but most simulate mining and reward small tokens, not actual BTC mining.
11. What’s the environmental impact of mining?
Mining consumes high electricity. Using renewable sources can reduce the impact.
12. Can I use renewable energy for mining?
Absolutely. Solar and wind sources are used in many large-scale mining farms.
