So, if the price goes up a lot, there might be some times within those kinds of periods that it goes down, but the mere fact that it might go down or that it is currently seeming to go down, does not mean that it will go down, so better prepared for UP in case you don't have any or enough coins, which again most of the world is in such a position, whether they realize it or not.
That's just it. Period.
While there's the decline and price falls and all of that, man this is Bitcoin, there's always that open tendency of an upward incline, most times a rather sharp one. While you do not have enough coins, or any, I think it's not wise to bank only on the fact the Bitcoin prices may drop, but also the way it can go up (We've seen that repeatedly overtime. ) as it could hinder us from investing in Bitcoin or adding [substantially] to our holdings.
