1- Nobody can monitor every bitcoin transaction there is. It is impossible. There are many online exchanges where you can use them as mixers. Nobody will be able to track you down.
Here is a record of all bitcoin transactions.
https://blockchain.info/2- You can convert your bitcoins into monero in the decentralized exchanges. If you feel insecure with the first way and the amount is too big to use on the exchanges, you can completely wash your coins with this way.
Good luck trying to track down monero transactions.
There will always be a way to circumvent the system and some will be able to get away with it. However the focus will be on any attempt to spend or exchange for fiat. Monitoring alt-coins is just not cost effective. But monitoring every blockchain entry that ends in a cash settlement or purchase is. Evasion will get harder and harder and more risky as time goes on. And again, for what? Why risk jail when you are profitable?
