Inflows into cryptocurrency investment products have exceeded $1 billion this year, driven by growing optimism around the potential approval of a Bitcoin exchange-traded fund (ETF), according to James Butterfill, a senior analyst at CoinShares. This week alone, crypto investment products attracted $226.4 million in inflows, contributing to a month-to-date total of $482.1 million and a year-to-date total of $1.074 billion. Bitcoin accounted for the majority of inflows, with over $1 billion, followed by Solana with $119 million. Short BTC products saw inflows of $59 million. Ethereum and Tron, on the other hand, experienced outflows of $77 million and $51 million, respectively. Other digital assets, such as Cardano, XRP, and Litecoin, observed more modest inflows. ProShares’ Bitcoin Strategy ETF (BITO) has been identified as a beneficiary of the overall inflow into crypto investment products. However, it is expected to face significant challenges once spot Bitcoin ETFs are approved. BITO currently has $1.07 billion in assets under management and is on track to set a new trading volume record this week, with approximately $2 billion traded.
