Etf can contribute to btc price and according ot my understanding it can help with the adoption rate and Bitcoin will definitely pump but we should not expect a high price increase soon because it will take more time than we expect to come to a certain level because the drop was much higher than any other time but there are many evidence to believe that it will recover in the future so any investor today can certainly invest with confidence to make remarkable profits in the future but patience is significant because that is the main thing many doesn't have these days
