Right now the price is under 7300$ and earlier was over 7500$, we can't be sure 100% that a bull run already started, we need to wait more before bull run in my opinion.
In my opinion, we are currently in the early stage of the bull run of Bitcoin. In as much that the price of bitcoin moves up and drops down doesn't not necessary mean that the bull run hasn't started. Looking at the price of Bitcoin in January of this year and now, there has been a massive increase in the market value of Bitcoin. From $4k to $8k and you are not 100% sure that the bull run has started? What again do you need to be sure ??
