Odaily News The U.S. Securities and Exchange Commission approved the Grayscale Bitcoin Mini Trust's 19b-4 form last week. According to the S-1 filing released in March, the trust is code "BTC" and will be traded on the New York Stock Exchange Arca as a "spin-off" product of GBTC. Grayscale said that GBTC holders will see part of their holdings converted into the new fund, which is not expected to constitute a taxable event. (Decrypt)
