My grandma is dying. Should I pay her medical medical bills? Nah, I can afford to lose her. Jks.
The problem with investing is that some people will be very angry with themselves if they do lose their money. You naturally think "Argh, why did I invest in Bitcoin? I should have invested in xyz."
But as you say, you have to take risks if you want to earn big.
If shell die, just dont question her if she will pay you a visit.
