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??
Yes, you did the right thing OP. I believe our first role is to plant the seeds into their mind that there is indeed bitcoin that was created to help the whole humankind about its existence and to help the people against the overwhelming inflation that is increasing as much as almost twice annually.
But give your grandfather some advice again that he shouldn't put all his wealth into bitcoin because even if the profits is good, it's still risky to do it because its future is still not guaranteed although that chances are just slim. Risk are risks and it is still better to be safe than sorry. I'm afraid that someday in the future, when everything will fail, he will blame you because you introduced him about the existence of bitcoin.
