Where can I get list of privacy coins which I can invest on? Is it a good option to invest on these coins?
If you mean ones that promise privacy: almost all. If you mean ones that actually deliver: none whatsoever. If you mean ones that are at least trying and not outright scams: aside from bitcoin maybe one or two.
The popular privacy coin that I know is Monero.
"Monero (XMR) is a private, secure, and untraceable cryptocurrency that was launched April 18th, 2014. With Monero, it is said you are in complete control of your funds and privacy no one else can see anyone else's balances or transactions."
It is the ideal time to buy because it's bear market
