only speculation but no guaranteed it will happen. its only depend to vitalik how they think ETH 2.0 can help the market.
It does not really depend to vitalik but I agree he is a huge factor to be considered. The major factor here is the Ethereum 2.0 itself. If it is a success then surely many people will be hype and by ETH that will cause the price surge.
If the update is garbage then don't expect any price movement right after the release of the new version but I have high hopes to Vitalik work since the beginning.
I'm expecting ETH will reach again 0.1
BTC each on this upcoming update.
