Why would you take pleasure in the market going to hell? You speak of Vitalik not being in the best of mental states but it sounds like you are not either. If you care or not about money is one thing but wishing to see the market burn and having invested in it are counterintuitive and sound kind of insane when put together.
First everybody has different taste and different way to overcome their sadness and regret,he's that kind of person with an extreme personality.
but it's good for him and others,because they do not do something harmful to any other people unlike those scammers.
another one is vitalike,seems like you know nothing about that dude.
i am totally agree with his statement regarding this,even though he's smart but he acted like a retard sometimes.
that was why many people hated his project and his action,some people even said he's ped* or something like that because of his action and statement.
in the end it's ok if you are talking shit about something to make you feel better.
but of course it is ok as long as you do not bring harm to any other people
