Bitcoin miners typically operate within mining pools, sharing rewards when a block is discovered.
Profitability: Mining is generally profitable only with electricity costs below $0.05 per kWh.
Hobby Mining: Running a miner as a hobby contributes to the network, earning shared rewards, but likely less than electricity costs.
Key Questions About Bitcoin Mining
- How many miners are there? The exact number is unknown, as only mining pool activity is visible.
- 51% Attack Risk: A pool controlling a significant portion of blocks raises concerns, but malicious attacks are unlikely.
- Transaction Fees: Transaction fees are included in the overall block reward.
- Supporting the Network: Running a full node supports the network without high electricity consumption.
- Solo Mining: The chance of winning a block solo is extremely low; most miners join pools.

One individual’s experience highlights the risks of following cryptocurrency trading advice. This person claims to have lost a significant portion of their portfolio due to following the trading advice of someone who promoted various altcoins based on technical analysis (TA). The individual alleges that this person was silent when their predictions were wrong, but vocal when their recommendations led to gains. They also claim the advisor sold their Bitcoin holdings when the price rose from $3,000 to $5,000, predicting a subsequent decline.
This serves as a cautionary tale about the importance of doing your own research and not blindly following the advice of others in the volatile cryptocurrency market. Always consider your own risk tolerance and investment goals before making any decisions.

It’s crucial to understand that the information above reflects a snapshot in time, specifically on 10/09/2025. The cryptocurrency landscape is constantly evolving. Mining difficulty, electricity costs, the price of Bitcoin, and the dominance of various mining pools are all dynamic factors that can significantly impact the profitability and decentralization of the network.
For instance, the viability of hobby mining could shift dramatically if Bitcoin’s price were to surge, or if more efficient mining hardware became readily available. Similarly, the concentration of hashing power within a few large pools is a recurring concern that is addressed through various mechanisms, including the potential for miner self-regulation and the development of more decentralized mining protocols.
Furthermore, the example of the individual losing money on altcoin trading highlights the broader risks associated with investing in cryptocurrencies beyond Bitcoin. Altcoins often have lower liquidity, higher volatility, and less established track records, making them inherently riskier investments. Thorough due diligence, a well-diversified portfolio, and a realistic understanding of the potential for loss are essential for navigating the cryptocurrency market successfully.
Ultimately, staying informed and adapting to the changing dynamics of the Bitcoin ecosystem is paramount for both miners and investors. Relying on outdated information or blindly following the advice of others can lead to suboptimal decisions and potentially significant financial losses.
