Yes you are right it is just long term and trading will have so if it is not long term it is trading and if it is not trading it is long term and long term so far happens to be the best way to go about Bitcoin because of what it will give in the future after holding it. But the problem is that most people are so eager and interested in making profit in the short term which is not the best way to go about Bitcoin because you will either end up losing your trade or selling when you are not suppose to and should endeavor to invest and hold for long.
I don't understand why you are mixing Bitcoin holding with trading, if you are holding Bitcoin for a long term then you should not think twice otherwise your investment may be lost. You should limit yourself to holding Bitcoin only, holding Bitcoin for a short period of time can lead to losses. So holding Bitcoin for a long term is the most profitable and the benefits will be more, that's why if you want to hold Bitcoin for a long term then you must follow the DCA method to buy Bitcoin.
If you buy Bitcoin following the DCA method, it becomes much easier to keep it for a long time by buying it weekly, due to which buying Bitcoin using the DCA method definitely has the highest chances of success. Because the DCA method helps the most in buying Bitcoin deep.
