that's dumb statement, bitcoin is a currency and currency can be used for anything if the user want,just like people do use dollar to buy drugs or anything illegal? its the same like when you use btc,and about money laundering, its possible to be done through any currency, do you ever saw people buying a very simple painted canvas with only 2 colors like red and blue ? and they bought it for $5 million? do you think its normal or money laundering?
Yes, with exception that governmetns and banks control fiat. And they wont do anything to ban fiat. Why would they? they can print it at will and do whatever they want with it.
They dont control bitcoin, they cant print bitcoin, and they can cheat with bitcoin. This is a reason you see lots of negative press about bitcoin. Banks and gavernments dont want ppl to use it. Thus, the easiest way is just to scare ppl that bitcoin is only used by criminals or it is a scam.
