Or ya know.. Use privacy tools like you do for the internet. Email is sent over unencrypted communications but there are plenty of ways to make it private.
What's with this "we need something new" instead of improving what we have? Ready to jump into another new cryptocurrency that promises the latest and greatest "blockchain tech"? I thought you guys said Ethereum was gonna be the next big thing
Bitcoin is inherently not a privacy minded technology, being able to track every transaction ever is a feature, not something to discard. It's also a feature no 'privacy tool for the internet' (eg. tor) can easily change.
Bitcoin has too much momentum to plausibly be replaced in the near future. More likely is that bitcoin integrates ZKP-based cryptographic privacy once it becomes viable.
