I have nothing against Ethereum but base on your question if Ethereum was able to leave again with its current 3 figure value, my answer is I don't think so, I believe that Eth price grows further but it will not leave the 3 figure level. those Jan 2018 figure was very difficult to achieve especially in our present situation that the global economy was hit badly due to the COVID19 pandemic.
Same thought! I particularly prefer to use ETH in the market and I'm amazed by the movements of the ETH projects. However, look at the reality, even the upcoming event of ETH (ETH 2.0) and the developments of DeFi can barely help ETH to reach 4 figure value. Anyway, I still choose to invest in ETH since it has the potential to pump in the upcoming months.
