No, putting all belief in bitcoin is a mistake, all investors know that there is risk when we invest, so we never put all our funds into something. Maybe now we all see that bitcoin is a good place to invest but no one can be sure that bitcoin will continue to grow and survive in the future, the future is unpredictable. Risks in investment always exist, we need to be careful, putting all funds into bitcoin is like a gambling game. If we win, we will have lots of money but if we lose, we lose everything.
