I'm agreed with you. I also think that it is very much possible to money laundering via Bitcoin. You know right now Bitcoin is legal most of the country. Other Countries like or Asian countries are not taking any steps through Supreme court. People from Asia easily can launder there money to black market.I believe that they don't need to face any hassle to laundering money from their countries.
If the regulations are set in place there is no way anyone could launder money, with strict regulation the hopes of acquiring huge amount of bitcoin without being traced is just a dream, there are many cases being under the scanner and many culprits are brought to justice in this short period of time, people who does these illegal activities will continue to do so as they will find a new way to launder the money without being traced and blockchain is not the way to go for these criminals.
one of the reasons why most countries can not formalize the existence of bitcoin can be abused by people who are not responsible for money laundering and other criminal acts because bitcoin can not be regulated or approved by any central bank
