Crypto mining is harmful due to its massive energy consumption, leading to significant carbon footprints, air pollution (PM2.5, NOx, SOx) affecting human health, strain on power grids, and water usage, primarily driven by energy-intensive Proof-of-Work (PoW) systems like Bitcoin, although some newer methods and renewable energy use aim to mitigate this. It also creates cybersecurity risks like cryptojacking, slows down devices, and involves hardware waste, with impacts varying based on local power sources.
Crypto mining is operationally and financially risky. Mining hardware can break or become quickly obsolete, requiring downtime and expensive repairs. Fluctuating cryptocurrency prices and electricity costs impose additional financial risks that cannot entirely be mitigated.
Others use the heat from their own in-home cryptocurrency mining to spread warmth throughout their house. "I've seen bitcoin rigs running quietly in attics, with the heat they generate rerouted through the home's ventilation system to offset heating costs.
BTC. On average, it takes about 10 minutes to mine a single block of Bitcoin, and each block currently rewards miners with 3.125 BTC. Therefore, on average, it would take around 30 minutes to mine one Bitcoin under ideal conditions.
A focus on transaction fees: Since the miners will no longer receive block rewards for mining new bitcoins, their primary source of income will shift to transaction fees. These fees are paid by users to have their transactions included in the next block and are determined by market forces, such as supply and demand.
If you had invested $1,000 in Bitcoin five years ago (around mid-2020), your investment would have grown significantly, potentially turning into anywhere from roughly $9,000 to over $14,000 by late 2024/early 2025, representing huge returns, though it wouldn't have been a smooth ride due to Bitcoin's volatility and price swings. The exact value depends on the specific date you invested, as Bitcoin's price fluctuates, but holding it through its major bull runs and pullbacks would have yielded substantial profits.

British bank Standard Chartered projects that Bitcoin's price will reach $500,000 in 2030. Multiple prominent figures, including Coinbase CEO Brian Armstrong and Block CEO Jack Dorsey, have expressed their belief that it could reach $1 million or more.

At this point in time, there are about 19.5 million Bitcoins that have already been mined, while the maximum supply is fixed at 21 million Bitcoins. Considering all upcoming halvings every 210,000 blocks (~ 4 years), the last Bitcoins will be mined around the year 2140.
Bitcoin miners are noisy (50–75 dB) due to high-powered fans and hardware. Liquid cooling is the quietest option but expensive and complex. Soundproof boxes can cut noise by 20+ dB but need good ventilation. DIY enclosures work well if built with safe, heat-resistant materials.
Crypto and the Wash Sale Rule
The wash sale rule (also known as the 30-day rule) puts limitations on tax loss harvesting when it comes to stocks and securities. The IRS says that you must wait 30 days before buying the asset back. However, most cryptocurrencies and NFTs don't have this restriction.
Bitcoin mining, the process by which bitcoins are created and transactions are finalized, is energy-consuming and results in carbon emissions, as 48% of the electricity used in 2025 was generated through fossil fuels while 52% was generated through sustainable energy sources.
Taking a buy-and-hold position in Bitcoin five years ago would have delivered massive returns for investors. As of this writing, Bitcoin is up 962.3% over the period. That means that a $1,000 investment in the token made half a decade ago would now be worth more than $10,620.

The 10,000 bitcoin that software developer Laszlo Hanyecz paid for two Papa John's pizzas delivered to his Florida home on May 22, 2010, were worth about $41 at the time. Today they're worth $1.1 billion, as bitcoin hits record high prices.
