Bitcoin, Ethereum See Record Institutional Momentum as ETFs and Treasuries Expand Bitcoin and Ethereum continued to show strong institutional momentum this year, driven by record ETF inflows and on-chain signals suggesting more upside ahead. Bitcoin, which recently traded around $121,000, remains “ice cold” by one of its key valuation gauges, the Mayer Multiple. The indicator, which compares price to Bitcoin’s 200-week moving average, currently sits at 1.16, well below the 2.4 level typically viewed as overheated. Analysts say that leaves room for prices to climb toward $180,000 before reaching historically “overbought” conditions. Despite sitting at all-time highs, on-chain metrics indicate a calmer and more sustained market than in past cycles. Meanwhile, BlackRock’s iShares Bitcoin Trust (IBIT) has become the firm’s most profitable exchange-traded fund, earning roughly $245 million in fees over the past year. The spot Bitcoin ETF has amassed nearly $98 billion in assets since its launch 22 months ago, making it the fastest-growing ETF in history and positioning it to surpass Vanguard’s S&P 500 index fund (VOO) as the first to hit the $100 billion mark. Institutional interest has also expanded to Ethereum. Treasury holdings and spot ETFs now collectively hold more than 12.4 million ETH, or about 10% of the total supply. Treasury allocations account for 5.6 million ETH, while ETFs hold another 6.8 million ETH, showing Ethereum’s rising status as a mainstream institutional asset alongside Bitcoin.
