No measure can be taken, is that what you want to hear? If people think bitcoin is used to illegal thing then we just have to agree, if bitcoin is really going to serve its purpose, then it will definitely be used for illegal things, bitcoin is a currency and every currency is used for illegal things so bitcoin Will also be used for illegal things, the same way fiat currency is used for illegal things and I don’t know if anybody can stop that, but you know that their are lots of people using bitcoin for legitimate purpose.

Why are you not complaining that fiat currency is used for illegal things, why are you not looking for measures to be taken to stop fiat currency from being used for illegal things, or is fiat currency not not being used for illegal activities?
