You have to make a decision in a situation where you already have large chunk of your money on coin X which you obviously knew will moon any moment but then coin Y is already mooning, will you miss out? or sell coin X to buy coin Y?.
What if you sold coin X to buy coin Y and by the time you come back coin X have mooned pass your previous entry or even becoming a risky train to join? what if you choose to feign a blind eye on coin Y and coin X takes almost 15 or more days to start mooning?
While a thousand and one of such thoughts flood your mind on what to do.

I actualy do not know what exactly was said about idle money, maybe reductancy, maybe stagnation or just maybe statusquo and at some point gets spent and that becomes the entire life journey of idle money
