Hi,
Your question... is the question everyone is asking themselves. I mean we all wish to know which is the "good" crypto, where to invest, how to make the most of what we have, will we ever be millionnaires?
Spoiler: Nah.
The bitcoin community is far more than just a group of crazy investors. I understand your concern but I cannot answer. Try to mitigate, only invest what you can afford to lose... But keep in mind that you will not become rich with bitcoin. If ever it happens it will be a good surprise and otherwise... well, you will not consider bitcoin for what it is not.
Understand me, I am sure, bitcoin is full of opportunities. But not those beautiful stories we hear, it is already "too late" for that (which does not mean you should not invest!)
