I personally have been hodling Bitcoin for a period of time (>2 years), and there is no reason for me not doing so for the foreseeable future. I would buy more if the price keeps going down.
Keep in mind,very few people can make a profit in trading anything including Bitcoin.
Comparing to the whales, a retail investor lacks all the resources that can help him/her to consistently win in trading.
So my thoughts is that, hodl if you have believes in Bitcoin, and it is the best approach for retail investors, IMHO.
