I read a comment earlier about terrorists using Bitcoin and other crypocurrencies to fund their heinous acts.
Yes, of course terrorists can use crypocurrency. Anything the general public can use, will be used by terrorists. Cars, guns, USD, Bitcoin, etc.
This should not hold us back from innovation. This should not stop us from trying to do things better. This should not scare us, it should light a fire within us to make changes that help humanity as a whole.
