The complete transition to Ethereum 2.0 is expected to have a significant impact on the value of ETH, primarily through changes in staking and inflation rates. The shift from a proof-of-work to a proof-of-stake consensus mechanism will enable ETH holders to earn staking rewards, providing a new source of income and incentivizing holding. This increased demand for ETH, coupled with a reduction in the inflation rate due to the burning of transaction fees, is likely to drive up the value of the cryptocurrency.
