There are always risks in business and if you want to make BIG gains then you'll have to take BIG risks too. In last few months, Bitcoin hasn't moved much up or down after the January's hype and dump. So I don't think engaging in Bitcoin puts us at any risk.
I agree with you fellow. There is always risk in any type of business you indulge in. So, we must be ready not only physically but most of all, we must be emotionally and mentally be ready.
