Yes, this is the only privacy coin that I know of, Monero and then Zcash and Dash.

But obviously, Monero is top on the line, they even upgraded their network: https://www.getmonero.org/2022/04/20/network-upgrade-july-2022.html.

This upgrade will make Monero harder to trace and crack. So they remain one step ahead of the game as we all know that IRS offers bounty to software developers to break Monero.
