Why are we basing the next moves of the companies base on mere deletion of tweets only?
These are companies and for sure they will come back again sooner. They just didn't expect what happened maybe that's why they lost funds and there are many companies who lost funds in crypto as well so all of us are lost . They aren't bankrupt as of now so there is a chance that they will recover and come back.

With regards to your last question, we might enter the longest crypto winter or we might now but one thing is for sure though, that we are already in a situation where those who has cash left on their hand will be the ones who will get wealth after this bear market. We are in a survival mode for now and even those companies are. Companies going bankrupt, CEX halting withdrawals etc.
