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?

Yes i do believe on ethereum, the price of eth last january has already reach $1k dollars, that is the reason you should believe on eth that it can still grow in the future and you should hold your altcoins today.
