Crypto is great with its different capabilities and uses. But as long as the public is skeptical about the things it does, it will never be a mainstream way of life.
In my point of view we should use different social sites for spreading knowledge about cryptocurrency all over the world. Individually we can do many things for the promotion of bitcoin. By this way more and more people will come to know about cryptocurrency and to know the importance and benefits of it they will definitely invest in it and gradually the whole world will enter in crypto world.
