Note that GP stated they are "brainchild of cryptocurrencies". I don't think that the meaning you imply is what they had in mind.

"brainchild of distributed ledger tech and crypto currency capitalism" sure sounds like they are implying Coinbase almost invented cryptocurrencies. But English is not my native language so maybe I misunderstand it wrong.
In fact, I can't figure out a single thing that Coinbase is the best at in the cryptocurrency industry. So what do you mean with brainchild here?
