Of course I am holding on to my Bitcoins for the price increase, at the moment the price is on its way to $800 and when it hits that I am going to sell some coins that is for sure.
Not a bad choice. As for me, this kind of time is a really good time for trading because the price of bitcoin is playing around at $740-$790. Like many people are doing here: buy low sell high. The first and primary motto of traders, merchants even.
If you feel that price will go higher at the time of halving then you should buy some coins at current price so that you can make good profits by selling at the time of halving.
