I do not understand the main reason why I would sell my bitcoin if I am in a loss? Is it not better to store and save it for now?

Moreover my country local stores have never heard of bitcoin and probably will not do so in another two decades. So only way for me to use the bitcoin is to convert it to fiat and then transact on it or hold it long enough and then sell it.

Moreover my main job is always there. Bitcoin is a side/parttime earning for me and hence will not likely sell the coins unless I am in a big profit. Hence I will continue to increase my stash and keep storing
