Those who really benefit from the crypto currency are those who get a long time. from January 1, 2016, those who had bitcoins knew that the cost was then about $ 400, and by January 2017, 1 BITCOIN was $ 1000, which is 100% more. In January 2018, Bitcoin was 10,000 US dollars. Looking at this, selling will be the best option, because no one knows what will happen to the coin the next day, but those who held on to their BITCOIN now have over $ 18,000 for every BITCOIN they hold.
