After 78 days of outflows, Grayscale's spot Bitcoin ETF, GBTC, has seen net inflows for the past two consecutive days. This change in performance has led to discussions among market analysts. James Seyffart, an ETF Analyst at Bloomberg, speculated on potential reasons for this sudden shift, mentioning possibilities like short-term tactical trades or arbitrage trades. He also suggested that these transactions might have taken place in shorter time frames with lower transaction fees.
