Another Solo Miner Becomes a Lucky Winner
Last week, an incredibly lucky miner managed to find a Bitcoin block with only 10 TH/s, securing a reward of 6.25 BTC (approximately $141,875 at current prices). While the odds of this happening are astronomically low—one in 26.9 million—it highlights Bitcoin's democratic nature: anyone, regardless of resources, can discover a block.
But is solo mining worth the effort? Let’s dive into the fundamentals and evaluate whether you should take the plunge.
What Is Solo Mining?
Bitcoin mining involves validating transactions and adding new blocks to the blockchain by solving complex cryptographic puzzles (SHA-256 hashing). Miners compete to generate a hash that meets the network’s difficulty target.
There are two primary approaches:
- Pool Mining: Collaborate with other miners to share rewards proportionally based on contributed hashrate.
- Solo Mining: Compete independently to solve a block and claim the full 6.25 BTC reward (currently ~$141,875).
Pros and Cons of Solo Mining
Advantages:
✅ Full reward retention: No sharing with a pool.
✅ Cost savings: Avoid pool fees (typically 1–3%).
✅ Transparency: Direct payouts from the Bitcoin protocol.
✅ Independence: No reliance on pool uptime or trust in payout fairness.
Disadvantages:
❌ Extremely low odds: Requires significant hashrate to compete.
❌ High upfront costs: ASIC miners and node setup are expensive.
❌ Unpredictable returns: Potential for zero rewards over long periods.

How to Start Solo Mining
Set Up a Bitcoin Node:
- Download a full node client (e.g., Bitcoin Core).
- Sync the blockchain (requires ~400GB storage).
Acquire an ASIC Miner:
- Popular models: Bitmain Antminer S19 Pro, Whatsminer M30S.
- Expect costs ranging from $2,000 to $6,000 per unit.
Configure Mining Software:
- Options: CGMiner, BFGMiner, or EasyMiner.
- Connect your ASIC to your node.
Join a Solo Mining Pool (Optional):
- Services like Solo CK Pool or Braiins Pool offer solo mining with reduced setup hassles (for a fee).
Alternative: Peer-to-Peer Hashrate Contracts
For those deterred by high equipment costs, peer-to-peer hashrate contracts provide a flexible alternative:
- Rent hashrate for short periods.
- No long-term commitments or hardware investments.
- Coming soon to platforms like the Lumerin Hashpower Marketplace.

FAQ
Q: How much hashrate do I need for solo mining?
A: Realistically, 50+ PH/s to compete with large pools. Smaller setups (e.g., 10 TH/s) rely purely on luck.
Q: What’s the break-even time for solo mining?
A: With current difficulty and BTC prices, ROI may take years—if ever.
Q: Are there tax implications for mining rewards?
A: Yes. Mined BTC is taxable as income in most jurisdictions.
Q: Can I solo mine with a GPU?
A: Not profitably. ASICs dominate Bitcoin mining due to their efficiency.
Final Thoughts
Solo mining is a high-risk, high-reward gamble. While stories of lone miners hitting the jackpot are inspiring, the practical reality demands substantial resources and patience. For most, pooled mining or cloud-based solutions offer steadier returns.
