Crypto asset manager Grayscale has listed two new exchange-traded funds (ETFs) that offer investors a differentiated source of income through bitcoin’s (BTC) characteristic volatility.

The two New York Stock Exchange-listed funds will start trading on Wednesday.

The Bitcoin Covered Call ETF (BTCC) and Bitcoin Premium Income ETF (BPI) offer covered call writing strategies, which involves selling call options to generate income on the premium received.

Call options are derivatives contracts betting on the price of an asset rising. They give the holder the right, but not the obligation, to buy the asset at a predetermined price within a define period of time.

BTCC will write calls very close to spot prices to deliver income for investors seeking regular cash flow, with the options premiums possibly also providing a cushion against market downturns.

BPI meanwhile will target options with strike prices that are well out-of-the-money, meaning the price is much higher than the spot price. This would allow investors to participate in much of BTC’s upside potential while possibly benefiting from some dividend income, according to an emailed announcement from Grayscale on Wednesday.

The options contracts that both ETFs use will track other bitcoin ETFs, including Grayscale’s own Bitcoin Trust (GBTC) and Bitcoin Küçük Trust (BTC).

Despite the surge in institutional investment into BTC through spot ETFs since their introduction in January 2024, bitcoin’s volatility does not appear to be going anywhere for the time being.

After gaining nearly 48% in the fourth quarter, the largest cryptocurrency kicked off 2025 by losing 12% in the historically bullish first quarter. It rose by 72% and 69% in the first quarters of 2023 and 2024, respectively, according to veri tracked by Coinglass.

Therefore, as institutional investors increase their exposure to bitcoin, there may be more demand for products such as Grayscale’s that can offer differentiated sources of income to cushion against this volatility.
