Just want to point out I'm not paranoid about anything, because I don't store a single satoshi of my money on a centralized exchange. Every exchange in the world can go bankrupt if they want - my bitcoin will be just fine.

I don't think it is. Binance started to publish their "proof of assets" bullshit last week. Then it all went silent. Perhaps they are scrambling to consolidate everything they can because right now they don't actually have proof of reserves. Or perhaps they are also having a liquidity crisis due to mass withdrawals, and are rushing to refill their withdrawal wallets. They could have done this gradually over the last several months and paid 1 sat/vbyte for it all, but instead they choose right now to do it and spend a huge amount on unnecessary fees to get it done? Not a coincidence.
