Table of Contents

Hi, I'm John. Today I'll be summarizing the latest news on cryptocurrency ETFs.

Hi, I'm John. As a blogger familiar with the world of blockchain and cryptocurrencies, I'm here to explain it to you in an easy-to-understand way. Today, I'll be sharing the latest information on the REX-Osprey and Defiance cryptocurrency ETF application.

As the cryptocurrency market becomes more active, there has been a surge in applications for ETFs (exchange-traded funds, investment products that can be traded like stocks). This has made it easier for institutional investors and the general public to access cryptocurrencies, helping the market mature. In particular, ETFs that incorporate staking (a mechanism for depositing assets into a network and receiving rewards) and leverage (a function that doubles investment returns) are attracting attention. If you are considering opening an account for the first time, it is a good idea to first understand the tips for choosing the right exchange.

This application was submitted on October 3, 2025, bringing the total to 27. The reason this is important now is that the emergence of ETFs for altcoins (cryptocurrencies other than Bitcoin) that go beyond Bitcoin and Ethereum is expanding investment options. In the past, the approval of a Bitcoin ETF revitalized the market, but now ETFs targeting a variety of assets are being applied for one after another, and the actions of regulatory authorities will be key going forward.

Background to the REX-Osprey and Defiance applications

REX-Osprey, a company specializing in cryptocurrency investment products, has previously launched a Solana (SOL)-related ETF. It has currently filed 21 spot cryptocurrency ETFs with the U.S. Securities and Exchange Commission (SEC) on October 3, 2025. These include single-asset ETFs such as AAVE, ADA (Cardano's currency), ATOM (Cosmos' currency), and ENA.

Meanwhile, Defiance, a company with a strong focus on leveraged products, has also filed for six leveraged ETFs. These applications became widely known when Bloomberg analyst James Seyffart shared them on X (formerly Twitter). The SEC's review process will now proceed, and if approved, new investment tools will be added to the market.

Details of ETF with staking function

Many of the REX-Osprey applications include a staking function. This is a system in which users can deposit their cryptocurrency holdings through an ETF into a blockchain network and receive rewards. For example, this applies to currencies that use Proof of Stake (PoS, a staking-based consensus method), such as ADA and ATOM.

In the past, staking rewards had to be managed individually, but now with this ETF, investors can automatically receive rewards simply by purchasing the ETF. As Coinpedia reports, this is likely to increase institutional investment in altcoins. More staking ETFs are likely to emerge in the future as regulatory clarity improves.

Features of Defiance's Leveraged ETFs

Defiance's six applications are for 3x leveraged investments (a mechanism that triples investment returns). They target major currencies such as Bitcoin, Ethereum, and Solana, and are aimed at investors seeking short-term price fluctuations. A CryptoRank article reports that they were filed on October 3, 2025.

Leveraged ETFs were popular in the stock market in the past, but they also pose a higher risk in cryptocurrencies due to their volatility. Currently, these products are primarily aimed at experienced investors. Going forward, regulation that takes market volatility into account will be important.

The impact of these ETFs

These filings could improve the liquidity of the cryptocurrency market (ease of buying and selling) and accelerate the participation of institutional investors. Coincentral's report emphasizes that the REX-Osprey ETF will use an offshore structure (a system using an overseas base) to ensure compliance (compliance with laws and regulations).

Just as the market soared following the approval of a Bitcoin ETF in January 2024, if these applications are approved now, it could be a factor in pushing up the price of altcoins. Going forward, attention will be focused on the results of the SEC review in 2025, but there is a possibility of delays due to the government shutdown.

Tips and tricks to remember when investing

Cryptocurrency ETFs are convenient, but due to the high risk of price fluctuations, please invest at your own risk. Legal regulations vary by country, and in Japan, please follow the guidelines of the Financial Services Agency. For security reasons, choose a trustworthy exchange and be sure to set up two-factor authentication. I do not offer investment advice, but the basic principle is to diversify your investments.

Here are some tips to help you put it into practice:

First, decide on the amount to invest based on your risk tolerance. Beginners are recommended to start with a small amount.
For more information on the ETF, please see the official prospectus. Please understand how staking rewards are calculated before investing.
Keep up with market news regularly, using trusted sources like Bloomberg and CoinDesk.
Don't forget to file your tax return. In Japan, cryptocurrency profits are taxed, so keep records.
