I'm not watching that video, but I have a feeling that there's not much science behind your claim.  Vitamin C has been shown to be able to reduce the severity of the symptoms of the common cold, but not the duration of the infection and it's my understanding that you'd need to have been taking it before you got sick and not just start when symptoms occur.  Anyway.

So much discussion about this virus and its effect on bitcoin--it's interesting to me what's happening, but it's also disheartening.  Is this going to end?  Yes.  Contagions don't go on forever, nor is this particular one extremely deadly.  But as I've said before, the fear is real and so is the effect on the economy, the stock market, and bitcoin as well.  I have confidence we'll get the virus under control and things will get back to normal--the problem is the uncertainty as to when that's going to happen.  The longer people are frightened and the more they sell their investments for cash, the worse it's going to be for crypto.

So far, the bitcoin crash hasn't been horrible.  Bad, yes, but it could have been (and could yet be) much worse.  The price currently is twice what it was at the beginning of 2019, so that's something positive.
