@MillionTokenCloud USDC is held by circle and coinbase. Grant Thomson said this: "Our responsibility is to express an opinion on the Reserve Account Information in the accompanying Reserve Account Report based on our examination. " We can't certainly know how much is coinbase is holding for USDC.

@0xb69308fba4929c57ad273641dff564efa743f09b As we saw in the market, usdc is more trusted, it unpeged above 1$ during this global fall down. ;) BUSD hold also. So maybe not the best stablecoin, but market speaks for itself. ;)
