Yes, investors are surely ripping their profits already as early as 4th week of October (last month) as bitcoin have reached another ATH.
But in the case of Tesla, it is just an estimated profit because Tesla haven't sold their bitcoins yet so it's safe to presume that it's just an unrealized profit or gain, maybe it's not their goal yet so possibly we can see another circus moves from Elon Musk to eventually force the value of btc to break another record this year or maybe not because they are trying to hold it for another few years.
Indeed those that bought bitcoin at the 30k region and below have gain massively from their bitcoin holdings and with whales like Elon musk and the president of El Salvador who just legalized bitcoin. In the near future more profits will be made from the price increase when it reaches 70k and above.
I have a slightly different point of view here because looking at the previous case, it is true that they can reap tremendous profits.
On the other hand, the manipulation that Elon uses and the Tesla that helped create Bitcoin a few months ago is actually intolerable.
but on the other hand we don't have any authority because indeed we can't prohibit and order someone to do something and that includes Elon and Tesla who use their influencer power to bring money and manipulation here
