The Securities and Exchange Commission has received a new application for a bitcoin exchange-traded fund. WisdomTree filed an S-1 with the Cboe bZx Exchange, intending to list its shares under the ticker BTCW. According to the filing, a custodian has yet to be identified, but Delaware Trust Company will serve as the trustee. Following a recent surge of bitcoinETF approvals in Canada, some market watchers are optimistic that the United States will soon follow suit.
