The whole "bitcoin can make us rich" hype is false context. It can make you rich but it it will not be overnight or permanent. You can cash in or cash out when the prices move sideways.
those people who bought bitcoin at its all time high at $20000 and decided to keep hodling until today will surely get depressed, regretting what they have done , can you called it as a bad luck? yes it is a bad luck and dumb uneducated greedy all at once.
to understand this business required an intense education -autodidactly- it is a bit complicated , this is not luck based business but people tend to think like that , easily get lured by how someone making $10000 from just $100 , dude you can not do the same over and over again.
there is no harm dreaming about getting rich through bitcoin investment as long as you do it full of responsibility.
there a lot of cases where people asked to join in bitcoin investment without any sufficient knowledge and only given a promise that it will grow hundreds fold! which in reality everything heading in the opposite direction, they lost too much instead get their investment growing. that is the common irony.
