Indeed you have correctly understood the usage of bitcoins, one should always hodl it for the long term rather than be effected by short term fluctuations and then indulge in panic sales. I feel we will see an increase in bitcoins prices soon in q1 as there're three major events to watch out for i.e. Bitcoins Nasdaq Futures, launch of Bakkt and the most likely approval of Bitcoins etf by sec. While the former two are guaranteed to happen, the latter may or may not happen, though sensing the mood of the public it may just happen and prices shall increase so a good time to be invested in bitcoins.
