Wow, I’ve got to admit, I don’t understand a thing about what you’re explaining. I get that you’re suggesting another crypto coin, but how all of that is supposed to work is totally beyond me.
I think this definitely calls for a beginner friendly guide!
For example, can what you’re suggesting be stored on a Ledger or Trezor wallet? That’s what I personally use.....
First, AAVE is a decentralized lending protocol that as of right now has around $20B worth of coins on it (collateral, deposits, etc), that's why I said this one and not another one. You can deposit your USDC on it, which gives you a new token called avUSDC (may vary depending on blockchain), which is a yield bearing token of the USDC you originally deposited and can be swapped back to USDC at any time. avUSDC cannot be locked/frozen, and the underlying USDC is pooled/lent out, so while it can be frozen, it makes no sense to freeze as it'd freeze the whole protocol. So doing this you protect your USDC from being frozen, but at the same time you risk it by lending it out, possible protocol vulnerabilities, etc.
USDS is a token that is backed by other assets such as BTC, ETH, USDT, USDC, etc, generally stable assets as well as some real world assets like bonds. It has a value of $1 and it has a whole system behind it to keep it there, however, there's always risk of failure although it is very unlikely. You can swap your USDC for USDS at 0% fee (just gas fees) using their website, and USDS as far as I know cannot be frozen. It can be swapped back to USDC at any time too, and even convert it to sUSDS which is made by the same people and yields 4.5%.
Ledger's and Trezor's just store a key, you can store any token on them, maybe not natively on their own applications, but using Metamask or Rabby, you can add anything.
