Not so long ago, on November 24, Vitalik Buterin was the initiator of the EIP-4488 improvement, which, according to calculations, should lower the gas price in the ethereum network by about five times. Until this time, the very global improvement of Ethereum 2.0, launched on December 1, 2020, also assumed, along with other improvements, to solve the problem of high transaction fees. If Buterin is still looking for other options, then is he really not sure about the effectiveness of what was previously conceived, or is this a common reassurance due to the severity of the problem? Anyway, I believe in Buterin's team and his ethereum coin, as they are constantly working on the existing problems of their cryptocurrency and suggesting new original methods of solving them.
