Honestly, leaning too hard on USDC just because of "transparency" is kind of naive at this point. Circle’s compliance game is tight, sure — but don’t forget they froze addresses before without court orders. That level of control isn't exactly what crypto's about.
And USDT? Dominates because it’s useful, not because it’s ideal. The fact that it's still the go-to despite all the FUD should tell you something — it's battle-tested. But neither are perfect.
Splitting between the two sounds more like hedging fear than having a real strategy. If you're just parking capital, why not look at DAI, sDAI, or even something like RAI or GHO if you're feeling experimental? At least then you're supporting protocols that lean closer to decentralization.
