Speaking of the discourse and ideological differences between Bitcoin and altcoin, former Coinbase CTO Balaji Srinivasan said that if you consider BTC as digital gold, I do think there is room for other things. I really don't want to argue with people who think this is a "zero-sum game." There are zero-sum games, but I don't think BTC and altcoins are "zero-sum games." Our philosophy is "BTC and" rather than "BTC or". Coinbase, no matter whether I am in a private coin or a smart contract community, everyone knows, respects and holds Bitcoin.
