Grayscale Investments CEO Michael Sonnenshein has suggested a significant development in the Bitcoin space, calling it the “main event” following a decade of preparation. Many speculate this alludes to the imminent approval of a Bitcoin exchange-traded fund (ETF) by the U.S. Securities and Exchange Commission (SEC). Although approval could come this week, experts like James Seyffart predict a longer timeline, possibly extending into January. The anticipation of a Bitcoin ETF has already impacted the Grayscale Bitcoin Trust (GBTC), narrowing its discount and potentially setting the stage for its conversion into an ETF.
