Top Altcoins to Watch March 3: Harmony, IOTA, UPCX & EOS Insights

Timing and knowledge are crucial for astute investors because cryptocurrency markets never sleep. A few altcoins are subtly creating waves as focus moves away from the typical titans like Bitcoin and Ethereum. They have exciting use cases, audacious ideas, and the potential to yield substantial profits. Today, Harmony (ONE), IOTA, UPCX, and EOS are notable for more reasons than just their names; they all find solutions to practical issues that draw in both seasoned investors and inquisitive newbies.

Harmony has emerged as a leader in addressing the critical scalability issues faced by decentralized networks through its innovative sharding-based blockchain. This technology allows Harmony to enhance efficiency without compromising on security or decentralization. Meanwhile, IOTA is redefining the landscape of blockchain technology with its unique infrastructure. UPCX is making its mark by disrupting the intersection of blockchain technology and traditional finance, while EOS is experiencing a resurgence after previously being dubbed an “Ethereum killer.” The increasing relevance of these coins stems from their ability to reflect evolving trends in the cryptocurrency sector, such as feeless microtransactions, scalable finance solutions, and interconnected ecosystems.

Harmony is focused on overcoming the challenges of efficiency and scalability that many decentralized applications face. Launched in 2019, it facilitates dApps by offering a consensus platform characterized by high throughput, low latency, and minimal costs. The “scalability trilemma” in blockchain—where security, scalability, and decentralization are often at odds—is tackled by Harmony through its Effective Proof-of-Stake (EPoS) mechanism and a unique sharding method. The current Fear & Greed Index stands at 30, reflecting a climate of fear and uncertainty. With a volatility rate of 12.68%, significant price movements could be expected in the short term. To bolster its ecosystem, Harmony has initiated a $300 million development fund and formed partnerships with prominent firms such as Animoca Brands and Chainlink. Additionally, the introduction of an NFT bridge as part of the Horizon Bridge has improved interoperability between Harmony and the Ethereum/Binance Smart Chain.

IOTA distinguishes itself from traditional blockchains with its innovative Tangle architecture, which is a Directed Acyclic Graph (DAG). This structure allows transactions to be processed in parallel, eliminating the need for miners and transaction fees. As more users join the network, security and efficiency improve, as each transaction confirms two previous ones. This design is particularly beneficial for Internet of Things (IoT) applications, where devices frequently engage in microtransactions without incurring fees. Recently, the token’s value rose by 6.17%, although it remains significantly below its all-time high of $5.69, indicating potential for growth as the project evolves. Additionally, IOTA’s collaboration with Japan’s New Energy and Industrial Technology Development Organization (NEDO) aims to incorporate distributed ledger technology and AI into industrial maintenance systems, targeting a share of the $1.5 trillion social infrastructure market in Japan.

UPCX is an open-source payment network that seeks to provide safe, transparent, and legitimate financial services on a global scale. It supports various financial instruments, including non-fungible tokens (NFA), stablecoins, user-issued assets (UIA), smart contracts, and cross-asset transactions, along with expedited payments. Similar to Ethereum’s standards, UPCX enables the creation and management of a variety of assets. It also features a Super App that acts as a comprehensive platform for payments, asset management, reservations, and more. Currently, UPCX has a market value of approximately $149.95 million, trading at around $4.06, with a 24-hour trading volume of $1.11 million. The present price reflects a 39% decrease from its peak, suggesting room for development as the project gains momentum. The UPCX DUBAI 2049 KOL TOUR is set to take place as a side event during TOKEN2049 Dubai, further boosting its visibility.

Once touted as a potential rival to Ethereum, EOS has undergone significant transformations since its inception. Launched in 2018 with a groundbreaking initial coin offering (ICO) that raised $4.1 billion, EOS aimed to address early blockchain platform issues regarding usability and scalability. Recently, it rebranded itself as Vaulta, signaling a commitment to merging traditional banking with decentralized finance (DeFi). This rebranding seeks to provide users with a seamless Web3 banking experience that bridges blockchain technology and conventional finance. As of May 3, 2025, EOS trades at approximately $0.7169, with a market cap of $1.12 billion and a 24-hour trading volume of $520.12 million. Recent trends indicate a bullish sentiment, with a slight increase of 0.56% in the last day, although this is still significantly lower than its all-time high of $22.83 from April 2018. Vaulta recently announced partnerships aimed at expanding its Web3 banking services and also introduced exSat, a Layer 2 solution for Bitcoin that addresses scalability challenges.

Solaxy is making headlines as the pioneering Layer-2 scaling solution for the Solana blockchain. Since its presale launch in December 2024, which raised over $33 million, it has set records as the largest ICO for Solana. Currently priced at around $0.001712, the SOLX token is pivotal to the Solaxy ecosystem. Early investors are encouraged to participate in the presale, where they can stake their tokens for an impressive annual percentage yield (APY) of 125%. The project’s roadmap indicates that SOLX tokens will be listed on both centralized and decentralized exchanges after the presale concludes in May 2025. With its successful presale and attractive staking options, SOLX is poised to make a significant impact in the cryptocurrency landscape.

Ultima aims to bridge the gap between conventional businesses and the cryptocurrency sector by providing a reliable platform that facilitates the everyday use of cryptocurrencies for transactions. The ecosystem includes features such as a crowdfunding platform, a modern cryptocurrency wallet, a unique debit card, and its own marketplace, creating a comprehensive financial environment. The price of Ultima has seen a 0.70% increase in the past 24 hours, indicating a favorable trend. Its substantial market cap and trading activity reflect investor confidence in the Ultima ecosystem. Ultima recently co-hosted the Blockchain Odyssey event in Dubai, highlighting its collaboration with BingX. Additionally, the introduction of a new Layer 2 blockchain network has improved transaction speeds and reduced fees, further enhancing the platform’s appeal.
