Trading is not a bad idea, same as hodling btc, most persons don't have the patience to Hodl btc for a long time, so it all comes down to the individual, we all know what works for us individually and as such we should focus on it, I personally will prefer the DCA strategy, because it has worked for me severally, I see every DIP as an opportunity to invest massively, but same can't be said to another person who thinks another strategy is better, so it comes down to the Individual and the experiences he or she has gotten.
