Privacy coins provide a discreet alternative to Bitcoin and other popular cryptocurrencies. By hiding the details of your transactions, they ensure that nobody can see how much crypto you’ve transacted – or, at least, that nobody can see where you’ve sent your crypto.

Zcash’s Zooko Wilcox has suggested that Zcash will have “default on, ubiquitous privacy”in the future. Similarly, the Zcash Foundation has considered making shielding mandatory—but this isn’t happening quickly. In either case, some jurisdictions may have an issue with Zcash because of its privacy features – Coinbase in the UK just removed the ZEC token from their listings, for example.
