> Cryptocurrencies (Monero, Zcash) with strong privacy protections usage prices soar

The private transactions in ZCash are very rarely used so any privacy leaks the article talks about should affect large parts of ZCash users as well.

Monero indeed is the best candidate so far with it's mandatory fungibility.

That's true! However unlike most cryptocurrencies, it's possible to send private transactions on ZCash so the point wrt price/usage still stands.

Wonder how many have tried to trace transactions done with Bytecoin / Monero? If nobody has been able to yet that would then render this a bit irrelevant in respect to cryptonote / cryptonight based currencies.

There was some research exposing vulnerabilities in Monero privacy tech[0], but AFAIK ringCTs and enforced minimum sizes of ring signatures fixes it.

It is a good point I hadn't considered that public cryptocurrencies are not fully fungible. I.e. It may be socially unacceptable to accept money from certain known people.
