I think we are already starting to see stability in the bitcoin price in the past few months, this can be caused by the ETFs. I believe that the more investment money flows into BTC, the more stable the bitcoin price would be.
We know that with better Liquidity conditions, prices are also more stable. Looking at current developments, BTC growth tends to increase in terms of adoption with the presence of Bitcoin ETFs. Along with the increase in BTC prices, the role of ETFs is also seen as being able to suppress volatility, but there are also negative effects if at any time they sell their BTC to the market, the reaction will be quite volatile, especially if the amount issued is also large.
