2 cryptocurrencies to reach $10 billion market cap in the second half of 2026

Stellar, specifically its native token XLM, recently saw a notable price increase following an announcement regarding a significant stablecoin integration. This development sees Stellar positioned as a launch partner for Open USD, a new stablecoin initiative reportedly supported by major financial players such as Visa and BlackRock. Such high-profile associations are seen as a strong validation of Stellar's utility as a foundational layer for large-scale digital payments and settlements.

Concurrently, unconfirmed reports have circulated suggesting that the Depository Trust and Clearing Corporation (DTCC) might consider XLM for settlement purposes. While these claims remain speculative, they have undoubtedly contributed to a surge in investor interest and demand for XLM. These narratives often precede significant price movements, and the focus remains on whether genuine utility can sustain this momentum towards a breakout.

Zcash (ZEC) has also been in the spotlight, experiencing upward movement as capital shifts towards altcoins, even as some institutional outflows are observed from Bitcoin. A key upcoming event for Zcash is the Ironwood network upgrade, anticipated in late July. This upgrade is specifically designed to enhance the performance of shielded transactions, which are a core feature of Zcash's privacy-focused blockchain. This technical improvement could act as a catalyst for ZEC's price, depending on broader market conditions at the time of its implementation.

Why it matters for Australian investors

For Australian investors, understanding these developments is crucial as they navigate the volatile yet potentially lucrative cryptocurrency market. The performance of altcoins like XLM and ZEC can significantly impact diversified crypto portfolios. While direct Australian dollar (AUD) pricing for every single altcoin can fluctuate rapidly, major Australian exchanges such as CoinSpot, Independent Reserve, Swyftx, and BTC Markets list a wide array of digital assets, making them accessible to local investors. Tracking these global trends is essential for making informed decisions on these platforms.

Stellar's integration with Open USD, and the involvement of global financial giants like Visa and BlackRock, could signal a broader acceptance of digital assets within traditional finance. For Australian investors, this could translate into increased liquidity and a more mature market environment, potentially reducing some of the inherent risks associated with newer, less-adopted cryptocurrencies. If Stellar solidifies its role as a key settlement layer, it could enhance Australia's participation in global digital payment systems.

Regarding Zcash, its focus on privacy features is a significant differentiator. While the Australian Taxation Office (ATO) provides clear guidance on the tax treatment of cryptocurrencies, including capital gains tax, the privacy-centric nature of ZEC does not alter an investor's tax obligations. AUSTRAC, Australia's financial intelligence agency, monitors transactions to combat financial crime, and legitimate ZEC holdings and transactions conducted through regulated Australian exchanges fall within these regulatory frameworks. Investors should always maintain meticulous records for ATO compliance, regardless of the privacy features of an asset.

Both Stellar and Zcash represent projects with distinct use cases and development pathways. Australian investors should consider the fundamental utility, technological advancements, and community support behind such projects. Diversifying their portfolios beyond just Bitcoin and Ethereum with carefully researched altcoins like XLM and ZEC can be a strategy for capturing different growth narratives within the dynamic crypto ecosystem.

Impact on the AUD market

The potential for Stellar and Zcash to reach a $10 billion market capitalisation could have indirect but notable impacts on the Australian dollar (AUD) denominated cryptocurrency market. As these assets gain prominence and potentially attract more institutional capital globally, it can contribute to an overall increase in the total value locked and traded within the broader crypto market. This general uplift can positively influence the demand for cryptocurrencies traded on Australian exchanges, providing more liquidity and potentially tighter spreads for AUD pairs.

Increased global interest in assets like XLM, particularly given its stablecoin integration, might encourage Australian businesses and financial institutions to further explore blockchain technology and digital payment solutions. If Stellar's solutions become more widely adopted internationally, it could lead to more Australian entities considering its network for cross-border payments, potentially impacting foreign exchange flows and the use of the AUD in digital contexts. Major Australian exchanges would be key in facilitating such integrations for local users.

For Zcash, while its direct impact on AUD trading volumes might be more niche due to its privacy focus, its projected growth reflects a broader trend of altcoin strength. As sophisticated investors look for diversification opportunities beyond market leaders, capital inflows into assets like ZEC can indirectly boost market sentiment. This positive sentiment can spill over into the AUD-denominated crypto market, potentially encouraging new retail and institutional participation across various digital assets accessible via Australian platforms.

Furthermore, the success of these projects can influence how Australian regulators, such as ASIC (Australian Securities and Investments Commission), view the evolving digital asset landscape. Positive developments in utility and adoption can contribute to a more nuanced and potentially supportive regulatory environment, which in turn could foster further innovation and investment within Australia's crypto sector. This could mean refined guidance or frameworks that benefit Australian investors and businesses operating in the space.

What to watch next

For Stellar, the immediate focus will be on further details and progress of the Open USD stablecoin integration. Confirmation of the reported institutional backing from entities like Visa and BlackRock will be pivotal. Australian investors should monitor official announcements from Stellar and the Open USD initiative, as well as any concrete developments regarding the unconfirmed DTCC settlement claims. The key is to distinguish between speculative hype and confirmed utility, looking for tangible signs of adoption that justify valuation growth. Continued performance as a settlement layer will be crucial.

Zcash investors should closely track the upcoming Ironwood network upgrade, expected towards the end of July. The successful implementation and subsequent improvements in shielded transaction performance could serve as a significant catalyst. Observing community reception and technical analyses post-upgrade will be important. Furthermore, broader market conditions, particularly capital flows between Bitcoin and altcoins, will play a crucial role in ZEC's short-term trajectory. Maintaining price levels above key support points will be a technical indication of strength.

More generally, Australian investors should continue to pay attention to global macroeconomic factors, broader cryptocurrency market trends, and any shifts in regulatory attitudes from bodies like the ATO, AUSTRAC, and ASIC. While forecasts of massive market cap increases are exciting, they are contingent on a myriad of factors. Staying informed about technological advancements, market sentiment, and regulatory clarity both domestically and internationally will be vital for assessing the long-term viability and investment potential of Stellar, Zcash, and other digital assets in the Australian context.
