IBIT coming in at #11 in April flows with $2.3b, baller number considering it's only ETF on list with negative YTD return. Typically only see that with Vanguard ETFs (their invs buy rain or shine). Good sign for long-term viability of category. Also notable DRAM at #12, unheard of for a newborn theme ETF to be that high.(Eric Balchunas)
