Crypto investors are anticipating the SEC's potential approval of spot bitcoin ETF applications on Wednesday. Fees for prospective spot bitcoin ETFs are already competitive, with many issuers waiving fees for the initial 6 months to attract investors. Fees range from 0% to a maximum of 1.5%. It's unclear how well a spot bitcoin ETF will track the price of bitcoin itself and bitcoin futures contracts. Performance will need to be monitored once launched. Initial inflows to spot bitcoin ETFs are estimated at $2-3 billion in the first month and $10-20 billion for the full year.
