When you make an investment decision you first need to consider if this is true and the chances of finding someone like that.

In many cases as time goes on the pool of people that will fall in this category become less until there is no-one left and then the price stagnates and become "stuck".  There are only so many people in crypto willing to take the risk and therefore "incentives" have to become really big and way-out to get more people interested. The people that misjudged the answer to the question in the link unfortunately have a problem and lose their money unless the theory becomes true again due to some intervention eg. even more way-out "incentives". In real life there are regulation against this.

You must therefore take care when making investment decisions and never invest any money that you are not willing to lose or you don't mind it becoming dead when it gets "stuck" when the pool gets saturated.
