You need to look at the problem in many directions, I've seen a lot of people change their lives completely by entering this market. The first is a friend who became a millionaire investing in bitcoin since 2014 - 2015, which was the better case for my friend. And then another case in this market, also another friend who went out of business when he entered the downtrend market, and he was involved in too many SCAM projects, that is the case, but it's not better.
Sadly some people are too impatient to wait until the market pumps bitcoin price, so they become desperate and start investing in schemes promising high percentage returns in short run. The result is a big scam and waste of bitcoins that could increase in value futurely. Actually bitcoin can make a person's life better if this individual is responsible and know how to manage his money properly, being patient during the whole process in a way he can enjoy his gains later, when the time finally comes.
Bitcoin isn't a magical token which make investors rich instantly. They still need to be focused and aware about the reality where you don't become rich overnight.
