- The Grayscale Sui Staking ETF operates outside the protective regulatory umbrella of the Investment Company Act of 1940.
- Investors face intense liquidity challenges because staked digital assets are locked up and cannot be sold quickly during market shifts.
- A complete loss of capital is a realistic outcome due to sharp price swings and reliance on third-party digital custodians.
A fresh set of financial filings reveals that the Grayscale Sui Staking ETF, trading under the ticker GSUI, skips the traditional regulatory frameworks that safeguard everyday investors. Unlike typical mutual funds or mainstream exchange-traded funds, this product does not register under the Investment Company Act of 1940.
Grayscale Sui Staking ETF ("GSUI" or the "Fund"), an exchange traded product, is not registered under the Investment Company Act of 1940 ("40 Act") and therefore is not subject to the same regulations and protections as 40 Act registered ETFs and mutual funds. Investing involves…

“By not adhering to this particular legislation,” writes financial analyst Marcus Vance, “investors do not receive the typical oversight from institutions.” Foreside Fund Services is responsible for marketing, while Grayscale Investments acts as the sponsor and works under the Securities Act of 1933.
This changes the whole equation when it comes to safety issues. The asset management firm has not registered itself as an investment adviser, thereby removing any protective measures for retail investors. This basically means that one has to be okay with investing money in something where he risks losing everything.”
The Illiquidity Trap of Grayscale Crypto Funds
The internal mechanisms of the fund reveal a multitude of weaknesses in its structure. Firstly, due to its lack of diversification into various sectors, this financial tool’s value depends on one particular cryptocurrency only. The absence of a diversified set of assets means there is no portfolio of different stocks to help cushion the effects of volatility.
According to Elena Rostova, one of the most prominent features of the fund, namely receiving rewards through staking, turns out to be its Achilles’ heel. In order to stake its assets, the fund needs to freeze them for certain periods of time during which they remain unmovable.
As a result, when the market starts crashing and plunging, there is nothing investors can do, neither sell nor move their money somewhere else, as they find themselves stuck with fluctuating prices and unable to take any actions regarding trading in the market. Aside from that, the fund faces some additional administrative issues since it is dependent on third-party service providers.
The Risks and Realities of Crypto-Asset Funds
If a major digital custodian and network validator experiences an outage, a breach, or sudden bankruptcy, investors may lose their tokens. In addition, the fund breaks away from conventional corporate finance traditions, where accountants determine the net asset value per share based on GAAP.
The fund makes it even more difficult to assess its financial position due to its reliance on its own valuation standards, instead of applying GAAP. In this regard, due to the fund’s use of an alternative set of accounting practices, as well as the vulnerability of the smart contracts and periods during which unstaking does not bring any rewards, the product lives on the edge.
