Well, it's nice to say 'move altcoins for BTC right before fall' but no one can predict such falls. But yes, I agree with the notion in general - is why I recommended BTC over altcoins in previous video given the fact that I suspected market to fall soon. It's nice when the market proves you right so quickly!

Alts don't tend to catch up, from my experience, until Bitcoin slows down (in either direction) so should be interesting to see if Bitcoin bounces back or has a sustained period of time of trading at lower prices. I'll be monitoring the situation closely, but for Bitcoin is likely the superior play when everyone is panicking. Thank you for the comment.
