Bitcoin changes many people's lives but not everyone will become richer, there are many people investing in bitcoin losing and losing a lot. Bitcoin is a highly profitable investment but needs analysis and research, if you buy bitcoin for $69k, you are currently making a loss, not a profit.
This is because they don't yet understand how the price of Bitcoin works, you don't buy when the price is up and has rise by a very massive number instead buy when the market is down like now and wait for the bull market for you to sell. People are easily moved by emotions that's Why when the price is pumping they rush to buy but stay away when the price is crashing that should have been the perfect buying opportunity.
Bitcoin has given people a reason for it to be trusted that's why it's the most preferred choice to other altcoins or alternative investment like stock or bond trading. Bitcoin is also one of the current investment that can give you high returns in a very short time and that's why it's of huge interest from investors.
