More moronic behaviour from the Binance casino:
Give them a taproot withdrawal address, they *literally change the address*, just changing the segwit version from 1 to 0, (valid because P2WSH length) because ... lol?
People sometimes say 'why do you care if the exchange does shitcoins?'. This is why. They just burned ~7.5K of this guy's money. He'll probably get it back because they're so rich they don't care, but he'll have to argue with them first.

Address where the permanently destroyed money went:
In 2017/2018 I got very militant about calling Coinbase traitors and incompetent and scumbags and so on; they all out attacked Bitcoin.
This kind of behaviour is a bit different: it only indicates they care so little that one dumbass decision from one noob backend engineer ('oh, if I replace p with q, it works!!') is the level of attention they pay to Bitcoin.
@waxwing Unless they decode it and then ignore the version and hardcode it to 0. Wow... I can totally see an engineer doing that.
@jb55 yeah, good Q.
It's 'human readable part', then 'version byte', then 'bech32 of witness program', where the third part gets the checksum property of the bech32 encoding. Why version byte isn't included in this encoding, and therefore in the checksum, (which after all is not relevant on-chain), I don't know. Maybe there's an obvious answer.
Perhaps the same reason the human readable part isn't included: to make it readable to the naked eye. (q vs p, here).
yeah I was just about to say, after looking at it again - my bad.
If you look, they actually swapped out the checksum. I'm not sure if this is worse or better!
