I would never be surprised if Institutions HODL big amount of Bitcoins. As a wise man once said, "If you can't ruin/break it, then control it". Well, If institutions will not at least manipulate and HODL Bitcoins it would cost them much as well.
We can see that Bitcoin is a threat to a lot of business industries worldwide and every institution are alarmed about this. I think they are probably HODLS a big amount and bitcoin to control it at least.
To me, that makes no sense
If you disagree and you think it does make sense, then you are welcome to explain how holding a big stash of bitcoins can help you control it. Further, you likely also need to explain how Bitcoin is "a threat to a lot of business industries worldwide". It is only a payment tool as well as a competitor to fiat, and while it may in fact pose a threat to a government monopoly on money printing, I don't really see how it can be a threat to real businesses apart from the banking industry. And even in the case of banks, things are not all black and white here
Well, a way to inflict some control on Bitcoin is by holding massive amounts, so when a fork happens, you can dump into whatever end of the split you aren't supporting, forcing miners to point their hashrate to whatever you are supporting and scaring them away from whatever you are dumping upon. So whales play a role in these fork-war situations. And Bitcoin is like land, it's limited in amount, there's only 21 million spots you can claim, no more, so if they want to outmatch the current whales, they need to hold more than them, and they can only do that by buying thus raising the price, and also hoping that whales capitulate when they manipulate the price down with Futures and other fiat derivatives
Well, now you add a new variable to the equation, i.e. a fork
Okay, you create a fork and dump whatever coins you are not quite happy with. And how's that different from just dumping your huge stash of coins making miners switch to mining something else, i.e. some other coin? Yes, that would likely crash the price depending on how many coins you actually have and probably even destroy it in the end if your stash is big enough
But does it make any sense if you have to buy up all these coins in the first place? Killing that coin would mean losing your investment, so you'd be basically shooting yourself in the foot. In simple terms, it doesn't look like control at all
