Where Should The Additional Support For HBD Come From? Bitcoin or something else?

@theycallmedan made an interesting proposal recently, should HBD follow the steps of UST and buy some BTC as a backup for HBD in time of crisis.

This does sounds interesting and it is in support of BTC and crypto, but the thing is when crypto goes down, so does BTC, so I'm not so sure will this have the effect we want, especially in a time of crisis.

Some other ways to back up HBD is actually buying some other USD backed stablecoin, USDT/USDC/DAI/BUSD, or maybe gold in form of PAXG? The gold narrative in crypto can be controversial, and PAXG is quite centralized I think.

Overall at the moment I'm thinking having a reserves from other stablecoins makes more sense. Actually UST is trying to achieve something like this at the moment by implementing a large 4pool on Curve, causing what is know as curve wars.

What are your thoughts?
