I learned to consider this kind of tweet FUD, doesn't matter the subject in question.
I tend to agree and it seems to me like a FUD, it seems like he warned people not to panic and hold their ETH, because seeing like this seems there's a dump, IMO.
It seems annoying seeing trusted people tweeting this random stuff, it seems like a clue.
Why do those people have a lot of drama, like CZ and now Vitalik?
Probably to get more engagement on the social media. I remember something similar happened in 2020 after the american elections. Several profiles who supported Trump continuously spread something was going to happen soon to revert the result, they had informations democrats would be exposed, the fraud was going to be exposed and so on... But only little vague informations were shared which were useful solely to boost those small, average profiles to a new level of recognization on the platform.
And now in my country the same is happening on the political field in the Twitter arena. I feel sad and unconfortable for people who believe on these internet guys.
