The whole point of Crypto is to get rid of Coinbase: “Commerce on the Internet has come to rely almost exclusively on financial institutions serving as TRUSTED THIRD PARTIES to process electronic payments. While the system works well enough for most transactions, it still suffers from the inherent weaknesses of the trust based model… What is needed is an electronic payment system based on cryptographic proof instead of trust, allowing any two willing parties to transact directly with each other WITHOUT THE NEED FOR A TRUSTED THIRD PARTY.” - Satoshi Nakamoto
