Methods to obtain privacy in Bitcoin: - Joinmarket (decentralized Coinjoin). - Payments with Lightning (payments through routing are totally anonymous, good method for example to put bitcoins coming from coinjoins in exchanges, you must open a private channel with a good node and through this route to the exchange). - Liquid Pegouts with sideswap (it is like a swap and you break traceability) - Bolts (swaps between chains and you also lose traceability) - Joinstr (Coinjoin through Nostr, soon to be released on the mainnet). - Mercury Layer (Coinswaps, soon to be released as well). - Bitcoin Teleport (decentralized Coinswaps with an architecture of makers and takers similar to joinmarket).
