My only question to all, was I able to give my grandfather the right advice??
Tension!

Tension!!!
It is not possible to say what the bitcoin market will look like in the coming days. If the market goes well and the bitcoin invested by your grandfather bring profit to your grandfather then it will be a reason to be happy for your grandfather. And if your grandpa's investment in bitcoin you advised him to make is a loss instead of a profit, it is doubtful whether your grandpa will be able to overcome the grief of the loss. If your grandpa dies due to over-tension then you will be the number one culprit and your grandpa will remain at risk of death for your advice.
