Stablecoins during the Merge

I'm mostly in stables during this market downturn, namely BUSD. From my DD, it's clear that only erc-20 BUSD is the stablecoin issued by Paxos, regulated in the state of New York and fully backed by cash and equivalent in FDIC insured bank accounts https://paxos.com/2022/04/07/busd-issued-by-paxos-on-ethereum-vs-busd-on-the-bnb-smart-chain/

Now there are lots of controversies surrounding the stable coins during the merge. The highly hypothetical and very unlikely worse-case scenarios claiming stablecoins on ETH chain could 'stay stuck' in the ETH smart contracts forever or lose their peg due to the potential PoW fork, negative funding and other problems with the stables on DeFi protocols.

Just trying to decide which chain to stick to with my busd during the merge. The way I see it, in theory higher technological risk is associated with ERC-20 BUSD than with BUSD on Binance Smart Chain. But then again, the depeg on erc20 BUSD would mean depeg on BSC Busd too - since there's only one price/ticker of Busd. Plus, as mentioned above, only erc-20 is regulated and insured.

So the only risk I see is that totally unlikely scenario where ALL erc20 stablecoins 'break down' during the Merge. What your approach to this?
