When people talk bitcoin seven or eight years ago maybe the person who heard it all fled, because at that time bitcoin was nothing, only a digital currency whose value was very cheap but had the ambition of uniting the world's currencies.

Only dreamers want to hear it, let alone dare to invest their money to buy bitcoin. But now, dreamers who are loyal to bitcoin and are willing to think about how to trade bitcoin intelligently, have become millionaires. While people who have opposed it now cry sad because they are still poor.
