Keep calm and HODL on
You are right, we should hold good item and wait for a good rate & we should not sell until it reach on our goal, it will be a wise decision and for that price also will increase.
Well, I am one of those who thinks holding assets is a pretty good way depending on the conditions. maybe there will be a time when we need to sell some of the assets we have. but, when it hasn't been seen, holding for long periods of time is not stupid thinking.
