Solo vs Pool Mining | 80% Chance of No Blocks Despite Positive EV

The Debate Heats Up

A growing number of people are diving into the solo versus pool mining debate, looking closely at expected value and the odds of yielding zero blocks. Recent discussions reveal that the probability of mining nothing can hit a staggering 80% even with seemingly positive outcomes.

Key Factors in the Mining Dilemma

Mining enthusiasts grapple with three critical probabilities:

• P(0 blocks): The chance of mining absolutely nothing over the year.

• P(loss): The likelihood of finishing in the red after covering energy costs.

• P(solo underperforms pool): The regret factor of choosing solo.

One hobbyist states, "I know I’ll never actually find a block, but I like the thrill of the chance," illustrating the allure of solo mining among certain folks.

Real-World Examples: The BCH Scenario

In a year-long scenario for Bitcoin Cash (BCH), using a modest setup of 9.4 TH/s, 200W of electricity, and a 1% pool fee, the math can get tricky:

• Electricity cost: $450

• Expected blocks over a year: Between 0.6-0.9

Despite the numbers hinting at possibilities, many may still end with no returns.

Interestingly, users find themselves balancing optimization criteria like long-term expected value against factors like entertainment and decentralization. As one commenter puts it, "With small hash setups, the expected value can differ greatly from median outcomes."

Insights from the Community

• Mining Preference: Some favor pooling a portion of their hashrate for better chances. One miner stated, "I send 80% of my hashrate to a pool and 20% to solo mining."

• Risk Assessment: Opinions vary wildly on what probability of zero blocks would prompt a withdrawal from solo mining.

• Personal Experience: The thrill of solo mining retains a loyal following despite the risks associated.

"Are you optimizing for entertainment or steady cash flow?"

Key Takeaways

• ◈ Probability of mining nothing can hit 80% for solo miners.

• ◇ Some mining setups show marginal expected value with high regret potential.

• ✦ Many people weigh thrill versus steady returns when choosing mining strategies.

What Lies Ahead for Miners

As the landscape of mining evolves, many believe we will witness a solid shift towards pool mining for most hobbyists. Experts estimate that approximately 70% of new entrants to the scene will opt for pooling strategies to mitigate risks. With solo mining yielding an 80% chance of blockless years, the balancing act between thrill and profit seems to be tipping in favor of collaborative efforts. This shift may also foster more engagement in forums as people share their outcomes and experiences, leading to refined strategies and new innovations in power efficiency and mining rig technology.

A Historical Lens on Risk and Reward

In the 1980s, the California gold rush saw a similar pattern among prospectors. Many bet everything on the chance of finding a gold vein, only to walk away empty-handed. Yet, those who pooled their resources created successful mining enterprises, ultimately yielding profits that individuals could not achieve alone. Just as those gold miners exchanged tales of fortune, today’s cryptocurrency miners are finding camaraderie in forums, weighing prospects, and making collective decisions about their risks and potential rewards.
