Your description is wrong. It's the not reason why bitcoin still not turn into global money. The main reason is all bankers are against bitcoin due to decentralized system. You can trace bitcoin if you know address won by who. Money laundering doesn't matter in my opinion. You know why? Most of money laundering, crime happening by real money, not by bitcoin. But the only matter is decentralized system, there is not controller that would control bitcoin. If you won bitcoin that means you are the owner of it. No organization there to control your bitcoin. That's why bitcoin still not yet turn onto global money.
