In the past few weeks, ETH has been falling, causing many people to be nervous. Some people sold their ETH at that time with the thought: "ETH is dead already."; "ETH will disappear." or "ETH will become a coin". And when ETH rose again they regretted "ETH has come back", "ETH will break in the next few months," "How stupid when I sell ETH."
I wonder if they really love ETH, love this crypto market? Or is it just trending? Do they have enough knowledge, psychology here?
What do you think about this?

there is no reason for ethereum to fail. There are many projects already using eth blockchain, it's nothing speculative. And still more and more companies intend to start using it, so eth is here to stay
