Soo in general how much should one invest in Bitcoin should it be "how much you can easily invest without stress " or "as much as you can invest at all cost"
Although I am aware it isn't a o or die affair
I think it's like asking how much cake to eat - there's no right answer, and it depends on your appetite for risk. I think understanding the market is necessary and only investing what you can afford to lose. So if you are a risk taker with deep pockets, go ahead and invest large sums. But if you are more careful and prefer to play it safe, it is better to invest smaller amounts.
