Actually the 8 reasons you talk about are quite reasonable. But I think these 8 reasons are too much. Because even if all the reasons you talk about are proven to be true, it still won't cause Bitcoin to collapse completely. Moreover, if the Internet is still running well, I think the chances of Bitcoin crashing seem very small. Although manipulation and monopoly in bitcoin do exist.

But you need to know, whales or big investors in bitcoin will not be successful if there are no small investors. Because bitcoin is an investment asset. And it won't work well if only one group plays a role.
