Maybe he wants us to be more careful in selling some of the coins we have in order to get big profits so that when we decide the wrong way there is no deeper regret, because we are often wrong in determining coin sales or purchases maybe when we just follow phomo without doing a fairly accurate analysis.
maybe that's the point, whatever decision we take is from the results of our own judgment even though we have received advice from others but we don't use it raw.
and whatever results you get if it comes from your own analysis, you won't be too sorry but if you use someone else's advice and you fail then you will be very sorry.
