The sec ETF announcement is around the corner which is scheduled for 27 February so I believe that is one of the reasons for the recent rise in the price, but in at that bitcoin depend hugely on positive news and media promotion which is capable of triggering the demands for the commodity which eventually result in the price rise.
The ETF decision being around the corner in my opinion can't be the reason for the increase on price Rather it should decrease.
The influence bitcoin ETF would have on bitcoin would be after sec makes tge decision
