way to help the development of bitcoin ie we promote bitcoin through social media and tell about bitcoin through television or radio. if at the moment I can only help the growth of bitcoin by telling my friends about bitcoin when hanging out with my friends.
Facebook and YouTube are good platforms but the problem is that most of the people around the globe still have this notion in their mind that the crypto currency is just a scam and it is not more than a software glitch, I think the more effective way is to make a wallet yourself and than communicate effectively on the social media, as well as people who are around you in your work place or near your home, once they will see you dealing in it and earning the profits, then it will give them a real confidence to start off.
