Almost all top altcoins or bitcoin that has a high volume in the market are all being controlled by the whale investors, just like what is happened into XRP a couple of weeks past, same goes with Bitcoin as well. There are lot manipulators in the market, and this things can't be gone anyway. I think it is already a part of their strategy anyway.
And you believe this is different with stocks? They are controlled by a small group of board member who together are the majority shareholders. This means that even if you were able to gather up all the other public shareholders you wouldn't be able to dictate anything or change company's policies. With Bitcoin you have the advantage because even if whales sell their stocks the technology will still be there. It will lose most of its value but it won't disappear. If the board decides to shut the company down it disappears.
