Many people became wealthy by Bitcoin and continue to be rich, but a lot of people gave up on it because investing in Bitcoin made them lose money when spending on it with no feelings whatsoever happening.
Yes bitcoin can make you and bitcoin can break you so as you said I will continue with saying that some people who were not very rich but they met bitcoin then they invest in it and hold so one day they sell at high price and got profit so again invested, waited and made money so this way a lot of people have become rich, but some people were so rich they spend all money in bitcoin then sell it at low price, they panicked and got huge lose so yes bitcoin have profit but it need patience to get rich with bitcoin.
