Lack of solid plans, more random decisions that are made in a very short amount period of time, in short, they lack patience or they got too arrogant to the point that they think that they can do anything because they have a lot of money. The other thing that I could think of is that they lack on financial management, like a good one, that is why they carelessly spend their money on to something they think that is a good investment but it turns out that it is not.
If it is about business, I think they made the wrong choice in their product, or it doesn't fit on the place where they started the business. If it is something like cryptocurrency maybe they invested in a project that is all about sugarcoated promises to fool people.
