Bitcoin's recent "halving" event has sparked a flurry of memes, thanks to its coincidental timing on April 20, a popular meme date. The event also marked 69 consecutive days of inflows for the largest US spot Bitcoin ETF. Despite a slowdown since their March peak, Bitcoin ETFs, including BlackRock’s iShares Bitcoin Trust, have not seen a day of outflows. However, recent filings have raised concerns about Bitcoin ETFs' mainstream penetration. In response, Bloomberg Intelligence ETF analyst Eric Balchunas suggested asset managers may treat these products like "hot sauce," adding just a bit to their portfolios.
