Controversies and Challenges
In the previous module, we analyzed the phases in which Bitcoin started to be mainstream, and its first difficulties. Now is the time to cover the topic of Bitcoin's controversies and challenges in depth.
The Bitcoin Block Size Debate and the Emergence of Bitcoin Forks
The block size debate emerged in the Bitcoin community in 2015 as a result of the increasing popularity of the cryptocurrency. The issue at hand was the maximum size of a block in the blockchain. The original block size limit was set at 1 megabyte (MB), and as Bitcoin gained popularity, the network experienced congestion as more transactions were processed. This led to longer confirmation times and higher transaction fees, as users competed to have their transactions included in the limited block space.
Many members of the Bitcoin community believed that increasing the block size limit was necessary to address these issues, while others were concerned that doing so could lead to centralization and compromise the security of the network. The debate became heated, with prominent figures in the community taking sides and advocating for their positions.
As a result of the block size debate, several forks of Bitcoin emerged, including Bitcoin Cash, Bitcoin SV, and Bitcoin Gold. These forks aimed to increase the block size limit to accommodate more transactions, with each fork taking a different approach. Bitcoin Cash, for example, increased the block size limit to 8 MB (later 32 MB), while Bitcoin SV increased it to 128 MB (now removed).
While these forks have their own communities and supporters, they also face criticism for being centralized and potentially compromising the security of the network. The block size debate and the resulting forks highlight the challenges and tensions inherent in decentralized systems, where different stakeholders may have competing interests and priorities.
Despite the ongoing debate, the original Bitcoin network continued to operate with the 1 MB block size limit intact (at least until the SegWit update). The Lightning Network, a layer 2 scaling solution, has also emerged as a potential solution to the issue of scalability, allowing for faster and cheaper transactions without increasing the block size limit.
The Regulatory Challenges Facing Bitcoin and Other Cryptocurrencies
As interest in blockchain technology grew, Bitcoin and other cryptocurrencies faced growing regulatory scrutiny. Governments and financial regulators around the world began to take notice of the potential risks and challenges posed by cryptocurrencies, including concerns around money laundering, terrorism financing, and consumer protection.
In 2013, the US Department of Homeland Security seized funds from the Mt. Gox exchange, citing violations of anti-money laundering regulations. This was a wake-up call for the cryptocurrency industry, and many exchanges and wallet providers began to implement stronger Know Your Customer (KYC) and Anti-Money Laundering (AML) policies.
In 2017, China banned initial coin offerings (ICOs), which are a way for companies to raise funds through the sale of cryptocurrency tokens. This move was followed by similar actions by other countries, including South Korea and the US Securities and Exchange Commission (SEC), which began cracking down on ICOs that were deemed to be securities.
In 2018, the European Union introduced the Fifth Anti-Money Laundering Directive (5AMLD), which brought cryptocurrencies under the scope of AML regulations. This required cryptocurrency exchanges and wallet providers to conduct KYC checks and report suspicious transactions.
Despite these challenges, the cryptocurrency industry continued to grow and mature, with more established players entering the market and traditional financial institutions beginning to offer cryptocurrency services. Overall, the regulatory challenges facing Bitcoin and other cryptocurrencies have highlighted the need for greater transparency and accountability in the industry.
Introduction of Bitcoin ETF
The introduction of a Bitcoin Exchange-Traded Fund (ETF) was a significant milestone for the cryptocurrency industry. For those who do not know, an ETF is a financial instrument that tracks the performance of an underlying asset or group of assets and can be traded on traditional stock exchanges. In October 2021, ProShares launched an ETF that tracks Bitcoin futures contracts traded on the Chicago Mercantile Exchange (CME).
The ProShares Bitcoin ETF provides investors with exposure to the price of Bitcoin without requiring them to hold and manage the cryptocurrency themselves. This is a major development, as it allows for a wider range of investors to access Bitcoin, potentially increasing demand and liquidity. A spot Bitcoin ETF, which would track the price of Bitcoin directly, does not yet exist but could be a valuable addition to the industry.
ETFs such as the ProShares Bitcoin ETF face their own set of challenges, including concerns around market manipulation and volatility. However, the introduction of the Bitcoin ETF was a significant step forward for the cryptocurrency industry. It demonstrated that Bitcoin was being taken seriously by traditional financial institutions, and helped to further legitimize the industry in the eyes of the wider public.
As more countries and institutions begin to embrace cryptocurrencies, it is likely that we will see further developments in the area of cryptocurrency ETFs and other financial instruments.
El Salvador’s Adoption of Bitcoin as Legal Tender
On September, 2021, El Salvador’s legislature passed a bill making Bitcoin legal tender, the first country in the world to do so. The move was championed by the country’s president, Nayib Bukele, who argued that Bitcoin could help promote financial inclusion, lower the cost of remittances, and attract investment to the country. The law requires businesses to accept Bitcoin as payment for goods and services, alongside the US dollar, which has been the country’s official currency since 2001.
The adoption of Bitcoin as legal tender is a significant milestone for the cryptocurrency industry, as it represents the first time a sovereign nation has recognized a cryptocurrency as a legitimate form of payment. However, the move has also been met with skepticism and criticism, with some experts raising concerns about the potential risks and challenges associated with using a volatile and speculative asset as a currency. Moreover, the implementation of the law has been met with some challenges, including protests from citizens and concerns from international organizations like the IMF.
Nonetheless, the adoption of Bitcoin as legal tender in El Salvador is likely to have a profound impact on the cryptocurrency industry and may pave the way for other countries to consider similar measures in the future.
