'Coinbase is a wolf in sheep memecoins.' That is hilarious!!!
You bring up good points about centralization. Coinbase is looking like it will be the dominant player in the crypto space. In their defense, they helped get crypto to where it is today and are fighting the SEC.

For those who want to play the game by their own rules, there will be MM, Trust Wallet, Rabby, and other wallets that haven't made any significant improvements in onboarding new users.
