This is somehow a great news for seeing another company joining on Bitcoin investment. But what's concerning on the action they made is they let the third party platform to held their accumulated funds.
If something bad happen on that exchange all of their efforts will be wasted and their company might get affected if there's bad situation happen. Maybe better for them to consider having safe wallet to stored their funds which they hold their keys.
So hopefully they consider that later on but anyways this is good start for them and hopefully they know what they are doing on the decision they made.
You don't need to worry about them because they are pouring millions of dollars into bitcoin and I believe the rich know very well what they are doing. Furthermore, they are big businesses and protected by law, so I think we are just worrying about them unnecessarily.
The tendency is that businesses in general start investing in Bitcoin. I don't think there are particular niches of the market to highlight right now. As we can see, Bitcoin has already went beyond the niches of informatics and technology. It's already entering the gastronomic one!
To me, bitcoin is a global asset/investment like many others. So anyone, company or organization can invest in it, not necessarily only technology and IT companies are interested and invest in it.
If they can invest in gold, stocks, bonds then investing in bitcoin is no different because bitcoin is also an asset like any other asset.
