There is no point in holding up bitcoin when prices are going down and you already buy it on a higher price. you have to sell that coin to reduce your margin of loss. Saving bitcoin for future is good but only if you have the guts to not to worry if the prices are getting too low.
There is only no point on holding your bitcoin if you are a panic seller, I mean just a temporary DUMP of bitcoin, and you have just sold it all because of being scared of losing your profits, but did you have a profit when you sell your bitcoins just because of a temporary DUMP?, NO, maybe yes but not a huge one, why? because you could have a larger profit if you didn't panic just because of a temporary DUMP, it is just normal, and bitcoins price would go back to normal in no time, most of the time its price goes up even more higher than its last price after its DUMP state.
So, if we are saving, and holding our bitcoins because we believe that it is a good idea to earn profits in the long run, then we don't have to panic every time that DUMP state happens to bitcoin, all we have to do is to relax and wait until it go back again on the way it is or even more, in that way, we could have a huge profit just like what we are expecting.
