I think if we save Bitcoin for a long time there is a chance of its fluctuated nature. So if we invest bitcoin instead of saving this will good. If we are risk taking personality we should save it for a long time in wallets. There are so many reasons to save it for a long time if we have huge amount of bitcoin and its price goes up there is a chances of growth in profits.
We cannot avoid bitcoin volatility but the longer we hold the better for us, do you think that somebody that invested in bitcoin when the price was 500 dollars cares that bitcoin goes back to 2500 of course not he is still in profits and may even take the opportunity to buy even more bitcoin.
