Bill should have a closer and deeper approach on this issue, because it will do him good as a potential investor that he is. Bill Gate is an individual expressing his personal opinion. He has the legitimate right to comment on major issue like this however I differ totally from his own opinion because cryptocurrency is best thing that happened to humanity in the most recent time. It's a time bomb to modern technology. Some people globally describe it as the smart economy of the people. Bill Gate should try with all possible best to adjust to this financial trend of technological economy.Though there had been some few bad issues here and there, the benefits of cryptocurrency outweigh the disadvantages. Thanks buddy for bringing such an interesting issue on stage.
