At present, we are aware of the importance of information in a rapidly changing society. In the past, if people who have acquired knowledge have made money, now knowledge is of course important, but in addition to this, people who acquire and deal with information quickly become better. If everyone has the same information, you know that it is not worth the information. Currently, the block chain technology is already on the way to life. But I can not say that everyone has accepted the coin as the same information yet, some accept it and some do not accept it. This can be seen by looking at regulations and attitudes of coins in each country.That is, coins are still worth it. Eventually the coin will be accepted. We do not always know at the time, but we often regret our past. We want to share our hope with those who are aware of this fact and still want to have a better future.
