Don't judge a book by it cover. In line with this, I would like to say, not to look at the external appearance of bitcoin and make bad comments. Many influential people or organizations are fantasizing about bitcoin. They say that making bitcoin transactions does not benefit the government. They have to comment because they are government employees. The government has asked for their report. They do not know that bitcoin cannot be allowed. To understand the importance of a book, the book should be well read. And to know about bitcoin, you need to know its usage. Those who invest and use know the importance of bitcoin. I think there is no alternative to currency like bitcoin. I have to say, bitcoin is the best currency in this world.
