# Bitcoin ETFs Analysis > Since the approval of 11 spot Bitcoin ETFs by the US SEC, over $1.5 billion has been invested in these assets, bringing the total ETF holdings to $28.3 billion. **Published by:** [Onchain Curiosity](https://paragraph.com/@thechriscen/) **Published on:** 2024-02-06 **URL:** https://paragraph.com/@thechriscen/bitcoin-etfs-analysis ## Content The US SEC approved 11 spot BTC ETFs on January 10, 2024. Since then, more than $1.58 billion in netflows have been invested in these assets. Among the 11 Bitcoin ETFs, Grayscale’s ETF (GBTC) has experienced the most substantial net outflow, totaling $5.8 billion. Conversely, BlackRock’s IBIT has attracted approximately $3 billion in net inflows, and Fidelity’s FBTC has gained $2.4 billion over the last 3 weeks. A good explanation for GBTC’s significant outflow could be its relatively high fee of 1.5%, leading investors to explore more cost-effective options like BlackRock and Fidelity, both offering a lower fee of 0.25%. Despite the outflows, GBTC maintains its top position among ETF providers, boasting a market share of 73.6%. Presently, GBTC holds 476k BTC valued at $20.5 billion in its ETF treasury. Following closely are Fidelity and BlackRock, each holding 62k BTC valued at $2.7 billion. Overall, the total value of all ETF holdings stands at $28.3 billion, representing 3.31% of the current Bitcoin supply. This analysis is part of my 100 Days of Crypto Data challenge.
