There are currently no active bitcoin ETF proposals in front of the SEC with VanEck, SolidX and Cboe BZX Exchange withdrawing...
According to reporting in CoinDesk last month money manager VanEck filed to create the VanEck Vectors Bitcoin Strategy ETF and last week that effort was given bad news by the SEC; the SEC sent a letter to VanEck stating that they cannot review the offering because "the underlying instruments in which the fund intends to primarily invest are not yet available."

ProShares and VanEck have both decided to withdraw their ETF filings with the SEC; VanEck filed for an actively managed Bitcoin Strategy ETF and ProShares said it was launching a suite of bitcoin ETFs; neither company responded to requests for comment; it is widely believed that bitcoin ETFs are the next step for the new currency.

Currently reconsidering the Winklevoss brothers' ETF proposal, the SEC has now received another approval request for a bitcoin ETF; investment manager VanEck has submitted a prospectus to the SEC for a bitcoin-related ETF; the fund differs from previous funds, with its investments based on derivatives of bitcoin; VanEck is seeking to list the fund on the Nasdaq and says it will also include conventional investments such as US Treasury bonds and cash for risk diversification.
