I think this prediction coincides with what many analysts are saying - halvings generally lead to bull runs later on. With the next Bitcoin halving in May 2020, we can almost certainly look forward to a bull run in the near future.
The main reason behind this is the theory of supply and demand. Halving is basically when the blocks of bitcoin blockchain crosses the number 210,000, the reward of miners get halved but they now have the hold of mined bitcoin which they can sell at higher prices. This increases the value of bitcoin eventually. But before that, a little decrease will appear and the rise also takes time.
thanks for that simple explanation . now i know if what really halving are . i cannot wait for this halving event to happen but its okay because we now have the time to prepare . we can buy now and start hodling , wait for that date to come and bingo , we guys can now harvest our gains . you said a little decrease will occur ? well that is a good news more evenly but why will the price decrease when people already start buying for preparation ? hmmm ..
