This forum is for opinion and perspective sharing. Should they rely on those who they don't even know? Confidence depends on someone's approach on what they see/what they hear. It depends on them whether should they trust Bitcoin or not. There are a lot of threads who explain why Bitcoin is such a good thing, yet we must not always see the bright side of a thing, hence must take a look on its cons and possible negative outcomes. Thus, our choice would be much enhanced as we further learn from it.

Invest and never hesitate. Yet first, learn to loose things, then soon you'll realize you are eventually learning from such small and big mistakes. Also, money must be used for you enjoyment and satisfaction and learning, not made only for storing it.
