Yea but not a constant percentage. A 50% in a month drop is much different than 10% drop of a much higher prices asset.

Anyway i would bet 2 bitcoin that it will not be down another ten thousand in a month. However im not aware of any escrow that would hold btc for one party and usd for the other as im sure you don’t want to bet in btc if you think that asset is dropping. Not without using some derivatives on eth that I don’t trust anyway.
