There's really no reason to be afraid of Bitcoin or digital currencies. Nothing is inherently scary about them. The fear comes from losing money, because you have to spend some to get in the game. It's a risk, and not everyone likes risks.
Yes actully every investment is a risk.
When we invest on something we need to have faith on it.
You cannot be scared after you invest ,actually the problem of salaried people is they just know that if they work only then thir money will grow.
What they miss is they donot understand that.Money can make money itself and some time its huge..:d
