Valkyrie has filed an S-1 registration form with the SEC to seek a listing of its Bitcoin spot exchange-traded fund (ETF) on Nasdaq under the symbol BRRR. The cryptocurrency fund manager is at least the fourth to apply for a BTC spot ETF in the last week, following BlackRock, WisdomTree, and Invesco. Fidelity is also rumored to be preparing to apply. Valkyrie already launched the second BTC futures ETF in the US and runs the Valkyrie Bitcoin Miners ETF that tracks securities of companies that derive their revenue or profits from BTC mining. Its application for a BTC futures ETF called the Valkyrie Bitcoin Futures Leveraged Strategy ETF was submitted on May 16. With competitors moving forward, Valkyrie decided to act despite the view of its CIO that a BTC ETF would only be possible “in a future administration after the next elections or through legislative action.”
