I personally believe that the bull run is influenced by certain factors and one of them is the influence of Elon Musk. Joining the bull run still depends on the user's preference on what to do with the current money/cryptocurrency he is hodling. Some people always watch the values fluctuate but does not do something about it because they want their money at the highest possible value which nobody knows when will come. Selling at that value is only reasonable because we can already gain great profit from it and we can use it however we see fit. We can multiply that money in creating a physical business because our options are endless.
