I know the world of cryptocurrency a few months ago from my friend. First hear my ears just a little weird about the world of cryptocurrency. But he explained cryptocurrency is similar with internet when it was created. Once upon a time the people doesn't care to Internet, but this time internet is a part that can not be separated by human life. Likewise with the world of crypto, in the present circumstances there are still many people who ignore and disregard it, But someday in the future the cryptocurrency will be a part that will not be separated from human life. For that reason I am interested to having business in the world of crypto.
