Bitcoin Criticisms & Counterarguments

Sep 13, 2025

Overview

This article reviews the main criticisms and counterarguments surrounding bitcoin as an investment. It addresses key issues such as volatility, payment efficiency, environmental impact, criminal use, intrinsic value, and competition from other cryptocurrencies. The article also outlines important risks and considerations for potential investors in bitcoin and other crypto assets.

Bitcoin’s Major Criticisms and Counterarguments

  • Volatility

    • Critics argue that bitcoin is too volatile to function as a reliable currency or investment. Large daily price swings are common, and bitcoin has experienced significant drops during bear markets, such as an 80% decline from its all-time high between November 2021 and November 2022.
    • Supporters counter that volatility is expected in the early stages of adoption. Research from Fidelity Digital Assets suggests that overall volatility is decreasing and may continue to drop as more people buy and hold bitcoin. Advocates believe that as adoption increases, price stability will improve and fluctuations will become less severe.
  • Payment Utility

    • Critics claim bitcoin is inefficient for everyday payments due to slow transaction processing times (about 10 minutes per transaction) and potential capital gains tax implications, making it impractical for routine purchases like groceries or movie tickets.
    • Advocates argue that while credit card transactions appear faster, they actually take days to officially settle, whereas bitcoin transactions are finalized in about 10 minutes. They also highlight third-party solutions such as the Lightning Network, which can process payments in milliseconds, and expect future innovations to further improve bitcoin’s payment efficiency.
  • Environmental Impact

    • Environmental concerns focus on bitcoin's high energy consumption, with some reports stating it uses more electricity than entire countries, such as Poland. Critics question whether bitcoin’s benefits justify its environmental cost.
    • Proponents respond that a growing share of bitcoin mining uses renewable energy sources. For example, as of late 2023, over 60% of mining reportedly used sustainable electricity. They also argue that bitcoin’s societal benefits may justify its energy use, especially when compared to other discretionary energy uses, such as holiday lighting.
  • Legality and Criminal Use

    • Skeptics worry that bitcoin facilitates illegal transactions, including money laundering and dark web purchases, raising ethical and regulatory concerns. There have been incidents where crypto has been used for illicit activities.
    • Supporters cite studies showing that the majority of cryptocurrency transactions are legal and that illicit use is likely lower than in traditional finance. For example, a report by a former CIA Acting Director concluded that criminal bitcoin usage is not higher than in the traditional banking system and is likely less. Additionally, bitcoin’s public blockchain makes illegal activity easier to detect, aiding law enforcement as digital forensics improve.
  • Intrinsic Value

    • Critics question bitcoin's intrinsic value, noting it is not backed by tangible assets and relies on perceived scarcity. Some view it as a speculative asset or even a Ponzi scheme, arguing that scarcity alone does not justify its value. They also point out that bitcoin has not been widely used as a currency as originally envisioned.
    • Advocates highlight bitcoin’s decentralization, fixed supply (only 21 million bitcoins will ever exist), and its emerging role as a store of value and hedge against inflation. They believe these features give bitcoin unique value, and point to some countries holding bitcoin as a reserve asset. Supporters also argue that bitcoin’s decentralized nature protects it from inflation and authoritarian control.
  • Competition

    • Some argue that alternative cryptocurrencies could surpass bitcoin due to more agile development teams and the ability to innovate quickly. Bitcoin’s lack of a central development team may make it harder to add new features or adapt to changes.
    • Bitcoin supporters see its lack of central control and first-mover advantage as key strengths. They believe bitcoin’s focus on being a decentralized, peer-to-peer payment network gives it a competitive edge over other cryptocurrencies that pursue broader applications. Its status as the most decentralized and established cryptocurrency is viewed as a major advantage.

Risks and Considerations Before Investing

  • Crypto assets like bitcoin are highly volatile and can experience significant price swings, making them riskier than traditional investments. They may also be more susceptible to market manipulation.
  • Cryptocurrencies lack the regulatory protections that apply to registered securities. The regulatory environment for cryptocurrencies is uncertain and may change, potentially affecting the value and legality of crypto investments.
  • Bitcoin and other crypto holdings are not insured by the Federal Deposit Insurance Corporation (FDIC) or the Securities Investor Protection Corporation (SIPC). Losses from exchange failures, hacks, or other issues may not be recoverable.
  • Security risks, such as exchange breaches, protocol flaws, or network-scale attacks, pose ongoing threats to crypto assets. Advancements in technology, like quantum computing, could also impact bitcoin’s security.
  • Investors should only allocate funds to bitcoin or similar assets that they are willing to lose, to limit the impact of potential losses on their overall portfolio.
  • External factors—including adoption rates, regulatory changes, investor sentiment, and technological developments—can all influence bitcoin’s value. There is no assurance that bitcoin will maintain its long-term value or that acceptance by mainstream merchants will continue to grow.
  • Bitcoin exchanges may suffer from operational issues, such as delayed execution, fraud, or security breaches. Assets held on an exchange that shuts down or is compromised may be lost.

Recommendations / Advice

  • Carefully review both the criticisms and counterarguments before deciding to invest in bitcoin. Consider the arguments from both sides and understand the unique risks associated with cryptocurrencies.
  • Assess your personal risk tolerance, investment objectives, and financial situation when considering cryptocurrency investments. Make sure that investing in bitcoin aligns with your overall financial goals.
  • Limit your exposure to bitcoin and other cryptocurrencies to an amount that would not significantly harm your overall portfolio if prices drop sharply.
  • Stay informed about the evolving regulatory landscape and security risks associated with crypto assets. Monitor developments in technology and regulation that could impact your investment.
  • Understand that past performance is not a guarantee of future results, and investing in crypto involves the risk of total loss. Make investment decisions based on your own research and circumstances.
