I know that for privacy purposes, Monero is the best crypto currency, but Monero is also harder to get and harder to use for payments.
What do you people think about the methods listed below of spending Bitcoin privatly?
Using the Lightning network: If you running your own node (could also be a prune node) then you have great privacy with Lightning, especially on outgoing transactions, because every lightning node only knows the before and the next lightning node.
The only threat here would be if your first and you last node in the chain work together to deanonymize you.
Using Coinjoin: you can just use Coinjoin for multiple rounds to get a very big anonymity set.
You can use a custodial crypto service as a mixer for coins. I would recommend coinos.io, cause they have very low fees and are accessible through the Tor Browser (they even offer onion links).
This should be combinned with a coinjoin or with multiple hops across different custodial services.
If you want to spend on lightning, coinjoin and then use the resulting outputs to open lightning channels.
If you want to spend on-chain, Wasabi Wallet has a new spending-friendly feature that lets you spend from inside of a coinjoin. That way you don’t have to pull the coin out, spend it and then start mixing the change, which adds an unnecessary transaction. The transaction that spends the coin is itself a coinjoin. I believe this feature is currently only available in the CLI but presumably it will be coming to the GUI soon.
This also gets into usability I would be shocked if we get monero to be accessible as a payment method in every day life without having to pay for a custom payment processor and going to a place that explicitly except menero with that payment provider. On the other hand I think their is a high probability we will get to the point where you can pay for every day item like clothes with bitcoin using paypal
