as @franky1 said using mixers to cover up your transactions will only make you look more suspicious and i agree with that considering that the government has labeled mixers as suspicious services and using these services makes you look suspicious.

and using a privacy coin will actually make your transactions more open, remembering that there is no such thing as a privacy coin because when the government forces developers to open access to their backdoors then they have to comply with this, like the sec did with monero.
