I agree on that, burning supply is one of the most common factor that can affect the price, it will make the price rise not only in ethereum but also in some any other altcoins, looking forward for the most bullish ethereum after this hard fork maybe the effect of this will take place 2 to 3 weeks after this successful hard fork.
If it is possible that the effect of the increase can last up to 3 weeks after this hard fork, then there will be many people who will benefit because now ETH coin enthusiasts have started to increase again and have also started to increase again so that it is very good for everyone with price resilience that will be very good on ETH.
