Yes, the London hardfork which is will take place tomorrow will be necessary for the ETH v2.0 and at the same time hopefully after the successful upgrade we can already enjoy lower gas fees. Something everyone is looking forward to.
Yeah, hopefully it will solved the high gas fees that everyone is complaining, specially with the whole swapping thingy.
On the other hand, ETH should also show a nice positive sentiment, and hopefully this event will act as an instigator to new ATH???
If it works by design upon it's released, for sure it will result in a positive sentiments. And we all know that if crypto enthusiast are happy, the price are going to soar in the next couple of days after that. So let's see, it might bring Ethereum to a new all time high, and as I have said in the other threads, it could have a ripple effect to other top altcoins as well.
