The impact on the ETH price
Because it will have a big impact on the way the Ethereum chain is being used, the impact that the London upgrade will have on the Ethereum price should be huge. By reducing the amount of ETH available at every transaction recorded on the ETH chain, the value of Ethereum will surely gain a multiplier effect on its price. Although everyone is sure about the positive effects that this upgrade will have, no one can really tell what will happen to the markets during the first days of the new protocol EIP-1559.
At last but not least, ETH will be still available on the market and tradeable via Yanda.io
. The new fork will not require any action from traders that will simply have to enjoy trading with a new powerful protocol of Ethereum.
