David Wachsman, president of Hawkeye Digital, emphasized that the return to profitability for average holders is critical. He noted that investors who have experienced losses often sell once they break even, indicating that this year's demand has had to contend with that selling pressure. With more average buyers now in the profit zone, it may become clearer whether institutions are looking to increase their Bitcoin exposure or simply capitalizing on the recent rally.
Interestingly, trading volumes painted a quieter picture, with the funds turning over approximately $4.5 billion, a figure that Seyffart described as not particularly high given the Bitcoin price movement. This volume was slightly below the $4.6 billion traded on the previous Friday. Balchunas mentioned that this trading volume was relatively elevated compared to stock and gold ETFs, with IBIT ranking among the top 10 by volume.
He also pointed out that the flows recorded for Monday likely reflect buying activity from the previous session, suggesting that the market's reaction to Monday's price movement is still pending.
Since their launch, cumulative net inflows have reached $56.16 billion, with the funds now managing a total of $110.14 billion, representing 6.30% of Bitcoin's total market capitalization.
"The resurgence of Bitcoin towards the $86K–$87K range is bolstered by renewed institutional interest, increased spot ETF inflows, and evolving regulatory conditions in the U.S.," noted Vikas Gupta, Bybit's country manager for India. He added that the market has remained resilient despite the Federal Reserve's recent rate hike and the failure of the Clarity Act, indicating that sentiment is influenced by factors beyond just monetary policy.
