The world is really changing from analog to digital, for example covid-19 pandemic really open people eyes to know that learning can also conduct online perfectly, which we believe on, and it works perfectly, secondly we stayed at home and watch football live at any country league and we believe on the final results score, even if you did not watch the match events, therefore some set of people say bitcoin is a scam, I think them need more knowledge to develop them self. Because world is really changing into digital.
