Reason people recommend monero is because crypto like bitcoin has a public ledger, so if you send your bitcoin to a usernet service then the usenet service and along with the exchange used to get the bitcoin will know what you spent the bitcoin on. So you end up having to use mixers to try and hide the transaction.

Monero is just easier where the wallet receiving the Monero should theoretically not know what address it came from because the ledger is private. So once you sent your monero into your own wallet the exchange and anyone you send the monero too would not know the address of your wallet or balance. At least in theory.
