Cryptocurrencies: Untraceable vs. Confidential

Here is a clear list of cryptocurrencies classified according to their level of confidentiality and anonymity:

Cryptocurrencies	Privacy Type	Explanation
Monero (XMR)	Untraceable	Uses ring signatures, stealth addresses, and RingCT to hide the sender, recipient, and amount. Considered the most anonymous.
Verge (XVG)	Untraceable	Uses Tor and I2P to hide IP addresses, and offers private transactions via Wraith Protocol.
Dash	Confidential	Offers a privacy option with PrivateSend, which shuffles transactions, but is not untraceable by default.
XELIS (XEL)	Confidential	is not untraceable by default. Offers advanced privacy features and complies with European regulations MiCA and DIC8.
