no.
if bitcoin was to drop from $525 to $52.50 (imaginary unicorn dream scenario)
people can easily buy 10 bitcoins for the same fiat as they were able to buy 1 bitcoin this week
and then use 10 bitcoins to buy the product that they strangely need right at the moment of some price drama
when the price crashes, it is not a time to start buying products or panic selling.
smart people know that price drama is temporary.
smart people know when the price drops. grab as many as you can at a discount
smart people know to only panic sell if the project is completely broke and will never work again
smart people know moving the early mined coins of 2009 is not breaking bitcoin beyond repair. bitcoin will continue and its just temporary price drama.
only a fool sells at a loss. only a smart guy buys at a discount
lastly.. people can happily use fiat to buy products.. but ETH is not really a retail use currency. it doesnt have thousands of retailers accepting it. and so
i would not suggest moving your bitcoins over to ETH. because you cant buy anything with it. and the price drama would make you lose out on chances to buy cheap bitcoin
