Bitcoin lacks consumer protections. It's actually not a good payment system in that regard. Those protections may or may not be necessary, but if the masses want them, they need to be built on top... maybe paypal is doing this?
That's precisely what I thought when I read "Coinbase Wallets" in the Braintree statement.
If Paypal only accepts Bitcoin from "verified Coinbase customers", they might as well offer buyer's protection / chargebacks etc.
