People passionate about privacy should just come to bitcoin and stop wasting their time on inferior protocols.
but bitcoin isnt private
Yes, but with privacy minded developers, better solutions can be made. Not even protocol changes are necessary, devs can create wallets that support BIP-47, for example, or we could have more development with LN privacy, which is pretty robust as is. Some shitcoins are more private than bitcoin, but they are a dead end. A more effective use of resources and time would be to work on the winning protocol.
