REX-Osprey’s Dogecoin ETF, ticker DOJE, opened on Sept. 18 and logged about 5.8 million dollars in its first hour of trading, according to Bloomberg’s Eric Balchunas as relayed by market coverage. That level exceeds typical first-day prints for new ETFs. Before the bell, Balchunas had set an opening-day “over under” of 2.5 million dollars in volume. He framed the bar as respectable for a debut.
