This is very irrelevant because the long term investment is not for panic selling and not to consider as short term because there are currencies which are favorable for long term and Bitcoin is the part of long term investment. If you are investing in Bitcoin in a low market then you must be waiting for long term and could get the profit but you did a mistake and sold out.
