There are many ways to get privacy in Bitcoin, if the fees are low coinjoin, if not low through Lightning and Liquid with swaps or peg-in and peg-out of Liquid. I don't use monero because it lacks monetary value and I risk losing money.
To each his own. Besides monero is a joke, if you want a private currency use zcash.
I hope zk-SNARKs can be applied to bitocoin someday through a layer 2 for example with Rollups.
Why is monero a joke? If we are interested in using these things as money instead of fiat, what do you mean by "has no monetary value" and "losing money"?
How is zcash better? From my understanding of zcash it's run by a for profit corporation, has a founders reward that goes to them, and privacy is optional which means private transactions stand out.
Coinjoin is not privacy, nothing is hidden, you are just obfuscating ownership even if you do it correctly.
Relatively expensive, tedious, and slow.
Bound by a small subset of users wanting to coinjoin.
Obfuscation degrades over time as outputs are spent.
Liquid doesn't hide sender/receiver, most blocks have 0 transactions so no anon set, and is custodial
Lightning is not private. Especially for receiving. Even LN devs are telling you.

Zcash has all the same problems of optional privacy. Novel cryptography. IP isn't hidden. Trusted setup. Dev tax. Going PoS. Blockchain was spam-bloated from 30GB to 260GB in less than a year (lol). Not used on DNMs for a reason.
