Are US exchange traded funds driving bitcoin's price rise?
Could you elaborate on the potential link between US exchange traded funds and the surge in Bitcoin's price? Is there evidence to suggest that these funds are significantly influencing the cryptocurrency's market movements? If so, how are they achieving this influence? Are they investing directly in Bitcoin or utilizing derivatives and other financial instruments? Additionally, are there any other factors that could be contributing to Bitcoin's price rise, such as increased demand from institutional investors or improvements in the underlying technology?
