Many are aware of crypto potential but they don't want to lose money, they re simply aware of its risks too, I have friends who aren't ready to lose a penny that's why they don't jump in yet and they like talking about the tech and the future possibilities
If they know the risk they should also be aware that someday the price of crypto will go down sooner or later. Before investing, you should prepare everything thoroughly without any hesitation at all, if in doubt you should avoid it because things that are forced will not be as good as investing in crypto.
