Actually read a news article that the Halving might not have cause the big previous bull run and might not have done it this time. Covered that in todays Analysis and News video https://youtu.be/dowwTpAd0-k

But looking at all world events: Money Printing, Trade Wars, Hyper inflation, COVID-19 and so on I expect a bull run coming. However it might drop first but I see the halving event as a possible contributor to a bull run of Bitcoin.
