Best holding policy is hold the bitcoin when the price is low and sell out some bitcoins when the price is high to make some profit. If you long term view about holding better hold your every penny of the bitcoin and utilize it on future.
Yeah its better to sell them when its allowing you to make profits instead of holding them too long as you never know what future holds for us but if we sell at higher price then it can give us profits and we can buy them again when price falls in future and I think that is the best way to play with bitcoins.
That's the better way of making profit but bitcoin has the possibilities of increasing much than decreasing in price. For this reason users who expect small profit could go with long time holding. Also as our bitcoins were in our own hands we doesn't need to panic.
Well we cannot really tell that, and how about if there's somethibg bad happen just like those bitfinnex hacking issue? Surely you will also dump your bitcoin if you will see its slowly soaring down, and im sure that many people doing some short trades at this moment and grabbing the merely down and ups of bitcoins prices, so i wonder how far it will go, but for now let see if the price up will continue to soar or it will stop and profits will soar down also.
