I would not agree that they think that way, because after all, they are the ones who have the most money, and in some cases, we are talking about the trillions of $ that such companies have under their management. For you and me, the price of 1 BTC is certainly so high that we can't afford to buy even 0.5 BTC without borrowing money from banks - but look at what Saylor (MicroStrategy) does when he buys a few thousand BTC every month.
I think some big players will only be interested in Bitcoin when it comes to their focus because of the incredible growth it is achieving compared to all other possible investments. And as time goes on, all those stories about Bitcoin being some kind of scam are fading more and more - some are starting to realize that phrases like "Probably rat poison squared" and "It's a mirage basically" never made the slightest sense.
