Monero (old struggling to keep up and stay private these days)
Not really. Can you point to an instance where a regular Monero transaction has been de-anonymized? And I'm not talking about via using data kept by centralized exchanges.
Monero is the synonym for privacy. It's the most used coin in darkweb. Other alternatives are not actually in use and some like zcash has documented vulnerabilities. I have no idea about what new techs are cooking on the privacy sector but monero has been a leader for quite some years and would continue to be in foreseeable future.
Privacy based coins might not be the ideal thing for normal investors or traders to deal with. As it would get more difficult to redeem then in and out in the future.
