GSR (Global Sourcing & Trading) has officially launched its first multi-asset cryptocurrency exchange-traded fund (ETF) — the GSR Crypto Core3 ETF, trading under the ticker BESO. Listed in the United States, it is the first US ETF to simultaneously offer exposure to Bitcoin (BTC), Ether (ETH), and Solana (SOL), while incorporating staking rewards into its strategy. The management fee is set at 1%, aiming to provide institutional and retail investors with a one-stop diversified crypto allocation.
Active Management + Staking Rewards
The BESO ETF employs an actively managed approach, adjusting its weekly weightings among BTC, ETH, and SOL based on proprietary research signals from GSR. This strategy seeks to capture excess returns while managing volatility. Unlike most existing crypto ETFs, the fund will generate additional income through staking eligible assets, offering a return source not solely dependent on price appreciation. GSR CEO Xin Song commented: “GSR has spent over a decade building efficient crypto markets, and with Core3, we are extending that expertise into a product accessible to a broader range of investors. Our ETF strategy reflects our deep understanding of how this asset class is evolving.”
Institutional Demand Driving Multi-Asset Strategies
As regulatory clarity improves and investor appetite grows, asset managers are increasingly exploring ways to package digital assets into familiar traditional financial instruments. Multi-asset strategies, particularly, are gaining traction as investors seek to balance risk across different blockchain ecosystems. Andy Baehr, Managing Director of Asset Management at GSR, noted: “As crypto becomes an increasingly important component of modern portfolios, Core3 provides exposure to the asset class’s primary drivers — Bitcoin’s macro influence and the continued growth and adoption of blockchain technology.” The launch marks a strategic expansion for GSR from its core market-making business into asset management, and signals a broader trend of crypto ETFs evolving from single-asset products to more sophisticated, actively managed multi-asset structures.
Market Impact and Competitive Landscape
The debut of the GSR Core3 ETF comes at a time of intense competition in the crypto ETF space. Previously, the market was dominated by Bitcoin and Ether single-asset ETFs. BESO fills a critical gap for multi-asset portfolio ETFs. With more players entering the field, future products are expected to incorporate even more complex features such as staking, leverage, and dynamic allocation. For investors, BESO offers a convenient gateway — instead of managing separate token positions, they can access a professionally curated crypto portfolio through a single listed instrument. Data shows that during the week of BESO’s launch, Bitcoin and Ether ETFs collectively saw net inflows of $1.36 billion, underscoring strong market demand for innovative crypto investment vehicles. GSR’s move is likely to further accelerate the convergence of digital assets with traditional finance.
