Missed the Bull Run? 3 Cryptos Under $1 That Could Make You Rich
NovumWorld Editorial Team
Ethereum Layer 2 tokens trading under $1 aren’t a guaranteed path to wealth, as these digital assets carry significant risks that investors must understand before allocating capital.
Three cryptocurrencies priced under $1 could potentially offer high returns as Layer 2 solutions are projected to facilitate a DeFi market reaching $256.4 billion by 2030.
Coinbase’s Base network has seen rapid growth, surpassing $14.9 billion in total value locked (TVL) by mid-2025, according to CoinMarketCap.
Investors need to carefully weigh the risks of centralization, security trade-offs, and composability challenges inherent in Layer 2 solutions before investing in these sub-$1 cryptos.
Centralization Risks in Layer 2 Scaling Solutions
Centralization in Layer 2 scaling solutions introduces single points of failure and censorship risks, potentially undermining the benefits of decentralization. Coinbase’s Base network has surged past $14.9 billion in total value locked (TVL) by mid-2025, but this rapid growth masks deeper centralization concerns.
Base, like many Layer 2 solutions, relies on a centralized sequencer. This sequencer acts as the gatekeeper for transaction ordering, potentially leading to censorship or single points of failure.
A core problem in Layer 2 solutions is sequencer centralization, which introduces single points of failure and censorship risks.
This isn’t just hypothetical. Consider the potential for regulatory overreach or internal bad actors.
If Coinbase faces pressure to censor certain transactions, it could theoretically do so at the sequencer level. This would effectively negate the supposed decentralization benefits of the underlying Ethereum network.
Understanding the trade-offs between scalability and decentralization is paramount for investors considering sub-$1 cryptocurrencies built on such platforms.
Layer 2 networks offer transaction speeds of up to 40,000 TPS and reduce fees by over 95% compared to Layer 1. However, security trade-offs exist.
CoinMarketCap notes that Layer 2 systems offering similar security guarantees as Ethereum may have limited scalability potential. Those with better performance might sacrifice security and increase centralization.
Investors must decide where their priorities lie.
Base’s success highlights the growing demand for faster and cheaper Ethereum transactions. Ethereum’s DeFi TVL surpassed $99 billion in 2025, according to CryptoPotato.
This is significantly larger than other Layer 1 ecosystems and underscores the need for scaling solutions like Layer 2s. It’s equally important to acknowledge that not all Layer 2s are created equal or share the same risk profiles. It is vital to research the specific architecture and governance of each Layer 2 solution before investing. Different Layer 2 solutions employ varying consensus mechanisms and security protocols, which can significantly impact their resilience and susceptibility to attacks. Furthermore, the concentration of power within a single sequencer raises questions about the long-term sustainability and trustworthiness of these networks. As Layer 2 solutions mature, the industry must prioritize the development of decentralized sequencer technologies to mitigate these risks and ensure the continued integrity of the Ethereum ecosystem. The pursuit of scalability should not come at the expense of decentralization, which is a core tenet of blockchain technology. The reliance on a single sequencer also raises concerns about potential manipulation or collusion. If the sequencer is compromised or controlled by malicious actors, they could potentially manipulate transaction ordering, censor certain transactions, or even front-run users, leading to financial losses. Therefore, the development of decentralized sequencer technologies is crucial for ensuring the long-term security and integrity of Layer 2 networks. These technologies would distribute the sequencing responsibilities across multiple nodes, making it more difficult for any single entity to control or manipulate the network. The concentration of power in a single sequencer creates a bottleneck, potentially hindering the network’s ability to handle large transaction volumes. This can lead to delays and increased fees, undermining the very benefits that Layer 2 solutions are designed to provide. Decentralized sequencers, on the other hand, can distribute the workload across multiple nodes, improving the network’s scalability and resilience. The industry is actively exploring various decentralized sequencer architectures, including those based on distributed consensus mechanisms and those that utilize a rotating set of sequencers. These approaches aim to distribute the sequencing responsibilities across multiple entities, reducing the risk of censorship and single points of failure. The development of robust and efficient decentralized sequencers is a critical step towards realizing the full potential of Layer 2 scaling solutions.
Liquidity Fragmentation Impact on DeFi Composability
Liquidity fragmentation across multiple Layer 2 networks complicates cross-platform transactions on the Ethereum network, hindering the seamless interaction between DeFi protocols. This fragmentation creates a less efficient and more complex DeFi landscape, hindering composability.
Consider a scenario where a user wants to move assets from one Layer 2 to another. They would likely need to use bridge protocols, which can be costly, slow, and introduce additional security risks.
This is far from ideal and undermines the user experience that DeFi is supposed to offer.
The projected DeFi market is expected to reach $256.4 billion by 2030, with a 43.3% CAGR between 2026 and 2030, according to CoinLaw. This growth hinges on seamless composability and interoperability between different protocols and chains, something Layer 2 fragmentation actively works against.
Ethereum’s dominance in DeFi, holding approximately 68% of the total DeFi Total Value Locked (TVL), according to MEXC News, means that fragmentation within its scaling solutions has a significant impact on the broader DeFi ecosystem. Instead of one cohesive market, users face a patchwork of isolated liquidity pools, each with its own set of tokens, protocols, and risks. This fragmentation can lead to increased slippage, higher transaction costs, and a diminished user experience, potentially hindering the adoption of sub-$1 cryptocurrencies operating within these fragmented environments. To combat this, developers are exploring solutions such as cross-chain messaging protocols and unified liquidity pools, but these technologies are still in their early stages of development and face their own set of challenges. The success of Layer 2 solutions ultimately depends on their ability to overcome liquidity fragmentation and create a seamless user experience across the entire Ethereum ecosystem. Furthermore, the lack of interoperability between different Layer 2 networks can create silos of liquidity, making it difficult for users to access the best prices and yields. This can also lead to increased complexity and confusion for users, as they need to navigate different interfaces and protocols to manage their assets across different Layer 2 networks. Therefore, the development of standardized protocols and interfaces is crucial for promoting interoperability and reducing fragmentation in the Layer 2 ecosystem. The fragmented liquidity landscape also makes it more difficult for decentralized exchanges (DEXs) to operate efficiently. DEXs rely on liquidity pools to facilitate trading, and when liquidity is spread across multiple Layer 2 networks, it becomes more challenging to execute large trades without experiencing significant slippage. This can discourage users from using DEXs and hinder the growth of the DeFi ecosystem. One potential solution to liquidity fragmentation is the development of “atomic swaps” between different Layer 2 networks. Atomic swaps allow users to exchange tokens directly between different chains without the need for intermediaries, reducing the risk of slippage and improving the user experience. However, atomic swaps are technically complex to implement and require significant coordination between different Layer 2 networks. Another approach is the use of “liquidity aggregators” that can route trades across multiple Layer 2 networks to find the best prices and yields. Liquidity aggregators can help to mitigate the impact of fragmentation by providing users with a unified view of the liquidity available across different chains.
Malicious Upgrade Risks in Layer 2 Protocols
Malicious upgrades across almost every Layer 2 solution pose a risk of user fund theft, highlighting a critical vulnerability in these systems. Jarrod Watts, Developer Relations Engineer at Polygon Labs, acknowledges this potential vulnerability.
Watts noted that “the worst-case scenario is an upgrade is performed that steals user funds… This kind of malicious upgrade is something that is possible on almost every layer-2 today.”
This is a critical point often glossed over in the hype surrounding Layer 2 technologies. While many focus on the scalability benefits and reduced fees, the underlying security assumptions are rarely scrutinized with sufficient rigor.
Watts’ somewhat comforting addendum – “over time, IMO the risk of malicious upgrades to steal user funds on layer-2s will be zero or very close to zero!” – offers little solace in the short term. In the world of crypto, “over time” can be an eternity, and the potential for irreversible losses in the meantime is a serious concern. The risk of malicious upgrades underscores the importance of thorough code audits, robust governance mechanisms, and transparent communication channels within Layer 2 projects. Investors should carefully evaluate these factors before investing in any sub-$1 cryptocurrency associated with a Layer 2 solution. Furthermore, the reliance on upgradeability introduces a level of trust that is often at odds with the ethos of decentralization. While upgrades are necessary to improve functionality and address vulnerabilities, they also create opportunities for malicious actors to exploit weaknesses in the upgrade process. The industry needs to develop more secure and transparent upgrade mechanisms that minimize the risk of fund theft and maintain the integrity of Layer 2 networks. One potential solution is the use of multi-signature wallets for upgrade approvals, requiring multiple parties to authorize any changes to the code. This would make it more difficult for a single malicious actor to execute a fraudulent upgrade. Another approach is to implement timelock mechanisms, which delay the implementation of upgrades for a certain period, allowing users to review the changes and raise any concerns before they are implemented. The reliance on upgradeability also raises questions about the immutability of Layer 2 networks. Immutability is a core principle of blockchain technology, ensuring that data cannot be altered or tampered with. However, the ability to upgrade Layer 2 networks introduces a degree of mutability, potentially compromising the integrity of the data stored on the chain. To address these concerns, some Layer 2 projects are exploring the use of “upgradeable smart contracts” that allow for upgrades to be performed in a controlled and transparent manner. These contracts typically include mechanisms for voting on upgrades and for reverting to previous versions of the code if necessary. Another approach is to use “zero-knowledge proofs” to verify the correctness of upgrades before they are implemented. Zero-knowledge proofs allow users to verify that an upgrade is safe and does not contain any malicious code without having to reveal the details of the upgrade itself.
Technological Risks: Polygon’s zkEVM Rollup Failure
Polygon’s zkEVM Mainnet Beta was quietly abandoned due to delayed technical execution and lack of product-market fit, according to CEO Marc Boiron, illustrating the significant technological hurdles in Layer 2 development.
Lorenz Lehmann, Ethereum Researcher, reported that Polygon zkEVM was quietly abandoned before the official announcement. It also never received a crucial upgrade to Ethereum’s “blobs”, according to Lorenz Lehmann’s report.
This raises serious questions about the viability of zkEVM technology, especially considering Polygon’s significant investment in its development.
Polygon spent $250M on its zkEVM pivot, according to a report by CCN.com. This demonstrates the inherent risks associated with betting on unproven technologies, even when backed by substantial capital.
The Polygon zkEVM rollup experienced an emergency state after the chain stopped processing blocks due to a reorg of the Ethereum mainnet. Blockworks reported that this outage highlighted potential centralization issues.
It also took around 14 hours for the rollup to reopen for withdrawals, affecting around 4,000 transactions. This real-world example serves as a stark reminder of the potential vulnerabilities in Layer 2 solutions, even those that are heavily marketed as “secure.” The abandonment of Polygon’s zkEVM rollup serves as a stark reminder of the challenges and uncertainties inherent in developing and deploying Layer 2 technologies. Investors should carefully consider the track record and technical expertise of the teams behind Layer 2 projects before investing in associated sub-$1 cryptocurrencies. The failure of Polygon’s zkEVM also underscores the importance of rigorous testing and validation before deploying new technologies on a large scale. The industry needs to learn from these setbacks and adopt a more cautious and data-driven approach to Layer 2 development. The incident also highlights the importance of transparency and communication. Polygon’s initial silence about the issues with its zkEVM rollup eroded trust within the community. Open and honest communication about challenges and setbacks is crucial for maintaining credibility and fostering a healthy ecosystem. Furthermore, the failure of Polygon’s zkEVM underscores the importance of diversification. Investors should not put all their eggs in one basket, especially when it comes to unproven technologies. Spreading investments across multiple Layer 2 solutions and other crypto assets can help mitigate the risk of losses. The failure of Polygon’s zkEVM also highlights the importance of conducting thorough due diligence before investing in any Layer 2 project. Investors should carefully examine the project’s whitepaper, team, technology, and community to assess its potential for success. The industry is actively exploring alternative zkEVM architectures that address the limitations of Polygon’s initial design. These include more efficient proving systems, decentralized sequencers, and improved fault tolerance mechanisms. The success of zkEVM technology ultimately depends on overcoming these challenges and building robust and reliable implementations that can scale to meet the demands of the Ethereum ecosystem.
Regulatory Risks: Impact on Layer 2 Crypto Investments
Regulatory uncertainty poses a significant risk to Layer 2 investments, as authorities scrutinize Layer 2 frameworks, potentially impacting their adoption and value. Nate Geraci, President of the ETF Store, notes the SEC’s investigation into Ethereum 2.0 and the need for further clarity from the IRS around the treatment of staking rewards.
While CryptoSlate reports that the SEC guidance removes a major regulatory obstacle for funds seeking to stake Ethereum, regulatory uncertainty still poses risks. Authorities are scrutinizing Layer 2 frameworks.
This scrutiny can lead to delays, increased compliance costs, and even outright bans, all of which can negatively impact the value of associated cryptocurrencies.
The SEC’s investigation into Ethereum 2.0 raised questions about whether Ether is a security. The investigation was later closed, according to a report by Forbes.
This uncertainty extends to Layer 2 solutions. These often rely on similar staking mechanisms or governance structures that could attract regulatory attention. The evolving regulatory landscape surrounding cryptocurrencies, particularly concerning staking and securities classifications, presents a significant risk for Layer 2 solutions and their associated tokens. Investors should closely monitor regulatory developments and assess the potential impact on their investments in sub-$1 cryptocurrencies. The lack of clear regulatory guidelines creates a chilling effect on innovation and investment in the Layer 2 space. Until regulators provide more clarity, the future of these technologies remains uncertain. The industry needs to engage proactively with regulators to educate them about the benefits and risks of Layer 2 solutions and to advocate for sensible regulations that foster innovation while protecting investors. The regulatory landscape is not static, and new regulations could emerge at any time, potentially impacting the viability of Layer 2 solutions. Therefore, investors need to stay informed and adapt their investment strategies accordingly. Furthermore, the lack of international regulatory harmonization creates additional complexities. Different jurisdictions may have different rules and regulations regarding cryptocurrencies and Layer 2 solutions, making it difficult for projects to operate globally. The regulatory uncertainty surrounding Layer 2 solutions also extends to the treatment of transaction fees and gas costs. Regulators may seek to impose taxes or other fees on these transactions, which could increase the cost of using Layer 2 networks and reduce their attractiveness to users. One potential regulatory risk is the classification of Layer 2 tokens as securities. If regulators determine that these tokens meet the definition of a security, they would be subject to strict regulatory requirements, including registration with the SEC and compliance with securities laws. This could significantly increase the cost and complexity of operating a Layer 2 project and could potentially limit the availability of these tokens to investors. Another regulatory risk is the potential for regulators to impose restrictions on the use of Layer 2 networks for certain activities, such as money laundering or terrorist financing. This could limit the functionality of Layer 2 networks and reduce their attractiveness to users.
Risk Management: Navigating the Layer 2 Crypto Market
Investors must exercise extreme caution when considering sub-$1 cryptocurrencies tied to Layer 2 solutions, due to the very real risks of centralization, security vulnerabilities, and regulatory uncertainty, demanding a risk-aware approach. Diversifying into established Layer 1 projects to mitigate risks is a more prudent approach.
This article is for informational purposes only and should not be considered financial advice. Cryptocurrency investments are volatile and carry significant risk. Always do your own research before making any investment decisions.
Chasing quick profits in the Layer 2 space is a fool’s errand. Prudence and diversification are paramount. Instead of viewing sub-$1 Layer 2 tokens as a get-rich-quick scheme, investors should approach them as high-risk, high-reward ventures that require thorough due diligence and a long-term perspective. Consider the potential for technological obsolescence, competition from other Layer 2 solutions, and the ever-present threat of black swan events that could wipe out entire crypto ecosystems. A well-balanced portfolio with exposure to both established Layer 1 blockchains and carefully selected Layer 2 projects is a more sustainable and responsible approach to navigating the complexities of the cryptocurrency market. Investors should also consider the long-term viability of the underlying technology and the potential for disruption from newer, more innovative solutions. The Layer 2 landscape is constantly evolving, and what is popular today may be obsolete tomorrow. Therefore, a flexible and adaptable investment strategy is essential for success in this dynamic market. Moreover, investors should be prepared to lose their entire investment, as the risks associated with Layer 2 tokens are substantial. Only invest what you can afford to lose, and never put all your eggs in one basket. The cryptocurrency market is highly speculative, and there are no guarantees of success. Therefore, a cautious and disciplined approach is essential for protecting your capital and achieving your financial goals. Before investing in any sub-$1 cryptocurrency, investors should carefully review the project’s whitepaper, team, technology, and community. They should also assess the project’s potential for adoption and its ability to compete with other Layer 2 solutions. It is also crucial to understand the tokenomics of the project, including the total supply of tokens, the distribution mechanism, and the potential for inflation or deflation. A well-designed tokenomics model can help to incentivize adoption and reward long-term holders, while a poorly designed model can lead to price instability and a lack of investor confidence. Furthermore, investors should be aware of the potential for scams and fraudulent projects in the Layer 2 space. There are many projects that promise high returns but are ultimately designed to enrich the founders at the expense of investors. Therefore, it is essential to do your own research and to be wary of any project that seems too good to be true.
