how come it hasn't affected the market yet?
Ethereum has increased from $ 350 to $ 600 in 1 month after the news about EThereum 2.0 was launched
What are the news are you talking about? Ethereum 2.0 was announced months ago, got several times postponed. They had collected enough Ethereum for 2.0 release only on November 24, but the price was around $600 before that happened. After that the price began to drop (but recovered later).
Look, before raising enough the price was $600, with Ethereum 2.0 release the price was around $600, and not it a bit higher thanks to Bitcoin growth. So where is the progress, improvement and growth?
