My grandfather has some wealth. Now my grandfather will invest all his wealth in Bitcoin. I told my grandfather not to invest all your wealth in Bitcoin. I suggested to my grandfather that Bitcoin not only has the potential for profit, but also the potential for loss. So you invest some wealth in Bitcoin. You don't have to sit on the street if your investment suffers.
My only question to all, was I able to give my grandfather the right advice??
And you are sure that you are telling us a true story? I have no idea how much wealth your grandpa has and whether he is forced to invest because it is his only way out of some problem, I don't know. But an older person saying that he is going to put
all his wealth into Bitcoin are the words of either someone who is in trouble because that wealth is by no means sufficient to cover future expenses or that person is not sane anymore for age related reasons or that person is this guy

and lied to you about being your grandpa, but in fact is not older than you.
