It honestly wouldnt surprise me. This twitter post doesnt have much evidence behind it. But other exchange coins did not perform similarly well during this years bear market (KuCoin Shares dropped from $20 to $1, for example). And there is no way BNB prices are resilient to cashing out to tether in a way that no other coin is immune.
it has plenty of evidence, Bitfinex'ed retweeted the posts and that guy knows everything!
