We should not call it a bull run. These are just some small rallies bitcoin made to create FOMO. Mostly done by exchange to liquidate future traders who open their position with high leverage.
Usually bull run start 3-4 month following the halving. In a bull run we don't see a major correction after rally. Bitcoin rallies and then little bit consolidation and then again rally. This continues till bitcoin cross its previous ATH and made a new one.[/list]
To be precise, it is a pre-bullrun created by fomo or maybe as you said, it was created to liquidate the majority of long/short orders in the market.
If based on history, it is true that the bull season will only come after a period of time after the halving, but there have been many questions about whether history will continue to repeat itself and the bull season will still take place after the halving? Because as we see, everything is becoming too easy to predict. Everyone is waiting to sell their bitcoin after the halving, so who will buy our high priced bitcoin?
