Don't predict or hope too much just because halving will happen next year 2020. Is it too early to predict what would happen next year 2020 after the halving or during the halving?
I think don't be conscious about the halving because halving is a normal state of the crypto which is happening every 4 years so there is no huge tendency that bitcoins will fluctuate and bounce back again around  $20,000 so it is kind of a merely prediction.
All we need to do right now is to stored bitcoins in our wallet so that we will be ready at some point if a bull run of bitcoin or market comes again. That was the best thing we need to do right now.
