Bitcoin spot exchange-traded funds (ETFs) have garnered significant interest, marking thirteen consecutive days of net inflows, with a total inflow of $48.706 million on May 30, according to SoSo Value. Notably, Grayscale's GBTC saw no outflows, while Fidelity's FBTC had an inflow of $119 million. The cumulative net inflow for Bitcoin spot ETFs has surpassed $13.809 billion.

BlackRock's iShares Bitcoin Trust recently became the world's largest Bitcoin fund, surpassing Grayscale Bitcoin Trust (GBTC) with nearly $20 billion in assets. Fidelity holds the third-largest spot with $11.1 billion. The launch of these ETFs has been a milestone for the crypto industry, contributing to Bitcoin's record high of $73,798 by March.

Bitcoin ETFs have amassed $58.5 billion in assets, highlighting their success despite concerns about the volatility of digital assets. While some countries restrict access to cryptocurrencies, institutions like Vanguard remain cautious about offering crypto products.

The positive trend for cryptocurrency ETFs extends beyond Bitcoin. The SEC recently approved spot Ether ETFs for issuers including VanEck, BlackRock, Fidelity, and others. However, analysts anticipate potential significant outflows for Grayscale’s upcoming spot Ethereum ETF, potentially averaging $110 million per day.
