Bitcoin already known and used worldwide. Sure the number of people who use bitcoin is still not as big as we wanted to but it is not small neither. I wish that Gox thing never happened. Because of that scam people got scared a lot and they see bitcoin as scam sadly.
how to make all people love this currency, and change bad image (scam) about bitcoin?
There is no way to make bitcoin become complete clean image the same way its very hard if not impossible to make the fiat money clean as we all know its being used for several deals on the dark marketplaces soo ,you can clean the mess around bitcoin but its about countries accept bitcoin as a currency and payment processor,till there the dark image will keep .Yes bitcoin its a currency that is being used by several people from several countries.
