If Bitcoin decreases then it's time to buy more Bitcoin.
Bitcoin dumped many times but still pumped back and surpasses the previous price so, then time Bitcoin's price dumped, I would choose to dump my Ethereum and other tokens abd buy Bitcoin.
Pretty spot on. If Bitcoin dips too much then it is a good decision to switch back from alts to bitcoin (maybe not ethereum, but most others certainly).
I believe in the technology for the long term, so a short term dip is nothing but noise when you zoom out and analyze without your emotions.
