how can you say it is "Official" when you are just relying on this Link?or is this a clickbait?to attract people clicking your Shared link that is why there is misleading in your title?
no one can assure the" Official Bull market" because it will only indeed once happen,even when time market is pumping no one can assured that this is bull until it reaches the top.
I think it will take some time for bitcoin to enter the bull market, we're just seeing a short up and down by price. So we have to be patient and be patient more before selling some bitcoin now. I'm sure that bitcoin's price will increase hugely after the halving though, we have to keep earning bitcoin for now and holding until the great news.
give it at least 3-5 months from now before we can have at least views on what market movement is really all about because for now?we are still waiting for the bull top come near.
