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??
Sounds like a horror story from r/wallstreetbets waiting to happen.
Never put money that you can't afford to lose into something. I'm not sure how much money your grandfather put into bitcoin but by the words of your post, it seems like a crazy amount of money. Hopefully, all goes well but good luck.
