According to a report by on-chain data analysis company CryptoQuant on February 14, over the past two weeks, more than three-quarters of new Bitcoin investments came from spot
Bitcoin ETFs (excluding Grayscale GBTC).
The report stated: "We estimate that over 75% of new Bitcoin investments come from these ETFs. Moreover, measured by realized
market value, investments from these ETFs have increased to 2% of the total historical investment in Bitcoin within just one month."
