VistaShares has launched BTYB, an actively managed exchange-traded fund (ETF) listed on the New York Stock Exchange that allocates the majority of its assets to U.S. Treasuries while using options strategies to provide weekly income and price exposure tied to Bitcoin.
As of Tuesday announcementthe fund allocates approximately 80% of its portfolio to U.S. Treasury securities and related instruments, with the remaining 20% ​​tied to Bitcoin (BTC) price movements through a synthetic covered call strategy. Holding data shows the fund’s Bitcoin exposure comes from call options on BlackRock’s iShares Bitcoin Trust (IBIT).
In this particular context, a synthetic covered call strategy uses derivatives to create price exposure to Bitcoin and sells call (call) options in exchange for that exposure to generate income, rather than holding Bitcoin directly. As a result, BTYB does not track Bitcoin spot prices and limits the upside potential in exchange for higher income from option premiums.
VistaShares says the ETF aims to provide about twice the yield of a five-year Treasury bond, although payouts are not guaranteed and can change weekly depending on options market conditions and changes in interest rates.
VistaShares is a US-based ETF issuer which focuses on actively managed funds using options strategies and thematic exposures, rather than time-honored passive index tracking.

Cryptocurrency ETF issuers go beyond products based on a single token
Other issuers have also launched U.S. exchange-traded funds that combine bitcoin with additional assets or broader baskets of cryptocurrencies, reflecting growing experimentation beyond single-asset crypto funds.
On December 19, 2024, the United States Securities and Exchange Commission (SEC) approved two spot cryptocurrency index ETFs, approving Hashdex’s Nasdaq Crypto Index US ETF to trade on the Nasdaq Exchange and Franklin Templeton’s Franklin Crypto Index ETF to trade on the Cboe BZX Exchange. Both funds have spot trades in Bitcoin and Ether (ETH) and track their respective cryptocurrency index benchmarks.
In January, Bitwise Asset Management launched the Bitwise Proficio Currency Debasement ETF, an actively managed fund holding Bitcoin, precious metals and mining stocks to address the withering purchasing power of fiat currencies.
ETFs that track a broader range of cryptocurrencies are also becoming increasingly popular. In September, Hashdex expanded its Crypto Index US ETF to include XRP (XRP), Solana (SOL), and Stellar (XLM). According to the company, the Nasdaq-listed fund holds five cryptocurrencies in a 1:1 ratio, including Bitcoin and Ether.
In November 2025, 21Shares launched two US-regulated cryptocurrency index ETFs: 21Shares FTSE Crypto 10 Index ETF and 21Shares FTSE Crypto 10 ex-BTC Index ETF. Both funds track the FTSE Russell cryptocurrency indexes and hold baskets of large-cap digital assets.
