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??
Now the most important thing is that you ensure maximum security on his computer. Because I am sure that there is an impressive amount, which means that we need: a powerful antivirus, a flash drive for storing passwords, a licensed verified version of programs and applications.
That's all is good, but the best thing he can do for his grandfather is to teach him how to detect scammers. It doesn't care if you have the best security if you are just sending your data or money to scammers.
