Changpeng Zhao of Binance became the first hero to blow the whistle.
I don't know the story here but I wouldn't even begin to consider CZ a "hero" since he is the same person who was offering payment to bitcoin mining pools in order to perform a 51% attack on bitcoin blockchain. All because his shitty platform was hacked and he wanted the money back.
And given that he (his platform) may have been the instigator of the huge mempool shooting up all of a sudden (if that was even Binance who was moving their coins around).
I mean goodness, who knows when that backlog is gonna be cleared...
