A BTC transaction can easily take 30 minutes to confirm. In that time, the price of BTC fluctuates and if there’s an exodus from tether to BTC, it could fluctuate a lot.
I find it very strange that crypto exchanges don't handle execution, confirmation and settlement in the same way as traditional markets.
Also, wasn't the major sell point of stablecoins to enable direct crypto-to-crypto transactions without ever needing to first settle in fiat currency, e.g. USDT -> USDC, as opposed to USDT -> USD -> USDC?
Precisely.

You don’t have to use an exchange to trade crypto. You can send crypto from one wallet to another without any exchange or anyone else in the middle (Except miners who are paid to confirm the transaction)
I'm not sure what he is talking about. On centralized exchangers execution, confirmation, and settlement happen nearly instantly. Unlike with stocks there is no 2 day settlement time.
For decentralized exchanges you can do it in 1 transaction executing both trades atomically. Modern token swaps will look for the optimal series of trades to make from available DEXs to give you the best rate. It can automatically check if it's better to go straight from USDT to USDC or if it's better to swap to bitcoin first. Sometimes it makes sense to split it up so some of it is direct swap and the other part of it uses an extra leg to get a better deal.
I’m not a big trader, but people send me BTC about once per week. It takes 30 minutes easily to get the transaction confirmed on the blockchain. Before that, it’s not clear the transaction is legit. And I have had one or two transactions that don’t reach the magic number of 6 confirmations. I’m not sure how the sender pulls that off, but I alert them of it, don’t deliver the goods, and they haven’t complained (knowing they sent a fraudulent transaction? I don’t know)
It’s my understanding those confirmations are being done by miners who get a small fee that me or the sender’s pay.I see this labeled as “network fee”.
The 30 minute wait would only make sense if you were to trade USDT for bitcoin on a CEX, then send that money using bitcoin to another CEX to execute the next trade to USDC.
