Never go full retard!! You can take any risk but never take risk with your MONEY!!
So are you implying that we should not have business or dive to an opportunity where we can increase our income? Businesses always take risk so people should also learn to take risk BUT they should learn what or where their money is going or how they really earn from it. Never take risk if you don't know what you're investing into, some people's mistake is this. They just invest in something just for the reason of someone told them that they would earn money from that.
