They are inching ever closer to the cryptospace, and while they are slowly creeping up to the space by means of VC funding, investors and institutionalists, they are still quite far away from the actual space and are just trying to test the waters by using indirect means of association with the actual market (futures market, etc.) Bakkt is one thing that's most sought after by the whole space, but even that is still far away from reality.
Well but that is a lot. Why? Because a big business won't do things suddenly and recklessly.
They need to analyze and test and test and test again to see if it would be good for whatever they want to achievement by doing it. Right now due to the really unstable nature of Bitcoin it's not really that attractive more than to invest and it's still a great risk for them. Because they might need capital later.
Capital is to a business what air is to us.
