Institutional adoption of crypto ETFs continues to evolve, with both Bitcoin and altcoins seeing increased product offerings and fluctuating investment flows. Morgan Stanley filed an updated SEC amendment for a spot Bitcoin ETF, naming Coinbase and BNY Mellon as custodians, signaling growing mainstream financial interest. 21Shares launched the first US Polkadot ETF (TDOT) on Nasdaq, expanding altcoin exposure beyond Bitcoin and Ethereum. NYSE’s parent company, Intercontinental Exchange (ICE), invested in OKX, further bridging TradFi and crypto. Despite this, spot Bitcoin ETFs experienced $228 million in outflows on March 6th, ending a recent inflow streak, while Ether, XRP, and Solana ETFs also saw minor outflows. However, overall weekly inflows remain positive at $917.3 million. Solana’s total payment volume surged 755% in 2025, demonstrating growing network utility. Bitcoin reserves on centralized exchanges have collapsed to levels not seen since November 2018, indicating a shift towards long-term holding, potentially creating a supply shock. Total assets under management in crypto ETFs remain above $90 billion.
