Once again, blockchains that use USDC continue to run without any serious outages for years. I just paid for an item with USDC (using Phantom Wallet) right now and there are many other examples of this.

No need to wait for a bank and it doesn't matter the blockchain, as long as it supports USDC and you have a crypto wallet, the payment goes through.

Stripe knows this already and crypto payments will be here for a very very long time as they already are today.
