OP how you and most of the people look bitcoin is very wrong. To start from the begining, problem are we, humans because we do illegal things. Next problem is money, fiat money, it's used in our everyday life and even bitcoin is calculated in USD value. Next problem is technology, let's blame technology before bitcoin. Without internet, computer and etc you wouldn't be able to use bitcoin so why not to consider technology as a tool of crime? I think with that logic that's the main reason and problem.
Then what about banks? Just see Deutsche bank and others, they were involved in money laundering and in other things. Also when does bitcoin comes finally? On exchanges, so let's blame exchanges because they give us possibility to exchange bitcoin into usd and other currencies.
So to sum up, that logic is "out of logic".
Everything has it's pros and cons and everything can be abused or misused, bitcoin isn't a problem.
