Cboe files to list what could be U.S.'s first bitcoin ETF

The Chicago Board Options Exchange (CBOE) has filed to list shares of VanEck's bitcoin exchange-traded fund, triggering the legal review period that could lead to the first bitcoin ETF in the U.S., CoinDesk reports.While Cboe's 19b-4 filing starts the formal regulatory review process, the 45-day review clock doesn't start until the SEC acknowledges that it's reviewing the application. Within that period, the SEC must either approve or disapprove the application or extend the review period.So far the SEC has rejected every attempt to launch a bitcoin ETF, including previous ones by VanEck.Bitcoin (BTC-USD) recently traded at almost $49K; down from its high of almost $56K on Feb. 22.Last month, Canadian regulators approved North America's first bitcoin ETF, which started trading on Feb. 19, with $165M worth of shares trading hands.
