Mainstream investment giants such as BlackRock (BLK.N) and Fidelity, as well as crypto-focused firms like Grayscale, have filed applications for spot bitcoin ETFs. U.S. crypto firm NYDIG estimates demand for a spot bitcoin ETF at around $30 billion. Their calculation compares the sizes of the gold and bitcoin ETFs - $210 billion versus $28.8 billion, respectively - and adjusts them for their relative volatility. BlackRock declined to comment on its pending spot bitcoin ETF, other than to confirm that it is still awaiting final SEC approval. His forecast is based on how demand evolved in smaller markets where spot bitcoin ETFs already exist, such as Canada.
