got it! this is the answer i'm looking for.
it makes sense to use USDT as a hedge and to park your earnings to buy low. but why not park it into USD instead of USDT? it seems like it would serve the same purpose. if you're concerned that the market will go down then sell off your btc for fiat USD, then buy back at the dip. is there a reason why USDT is favored over USD?
thanks. followed.
