It depends.

In some ways it can be more private than Cash, but a small user base means a small anonymity set and there have also been a few vulnerabilities in the past which have done damage to moneros privacy assurances.

Ultimately, the bigger problems are all the metadata which exists when using any form of digital money as well as the trade-offs made with ring signatures and decoy inputs/outputs which make it nearly impossible to verify the supply. Not to mention problems like data efficiency, mining clarity, or constant inflation.

If we said no to KYC, and used Bitcoin in a circular fashion and with the lightning network, its privacy would already be (pretty) good.

Monero is an interesting shitcoin and lots of ideas in it could make for a cool side chain, but it shouldn’t be taken to be 100% private without considering other factors and it will never be money on any large scale.
