Yes, its true, because many people have become rich due to bitcoin. They have done investments and have just waited for several years. But now it's not too late. Bitcoin is always increasing and your can get a good profit.
Do not be foolish to believe Bitcoin when it's turning into a demon. It goes up because the whales are trying to push it up, many greedy investors will buy it and think it will go up and keep going up. Do not make yourself a whale bait.
