Technically, no form of investment guarantees you safety, not even share marketing, mutual funds, and real estate.
After all, most people end up in losses.

Making money via sensible investments takes a lot of patience and persistence.
Sadly majority are not able to control their urges for losing enough (without any fault of their own).
The social media influencers, magazines are hammering people with quick-rich scheme-related content. This creates a FOMO too strong to keep resisting.

End verdict: Be it crypto or anything else, only a smart investor (a learned investor) will make money after showing enough persistence.
