The Dogecoin ecosystem has witnessed a massive influx of new investors after the first-ever U.S. Dogecoin exchange-traded fund (ETF) officially commenced trading last week.  The product opened to remarkable demand, recording $6 million in trading volume within its first hour — a figure 140% higher than Bloomberg analyst Eric Balchunas’ day-one forecast and nearly six times greater than the average volume for new ETFs over an entire session.
