Donald Trump has been touting his net worth of $10 billion, but Mavericks owner Mark Cuban questions whether that will actually help the real estate czar in his campaign to be the GOP presidential nominee.

In comments he posted through his Cyber Dust app, Cuban called Trump a "paper tiger." Here are highlights as compiled by the Dallas Morning News:

-- Let's say you own a painting that gets appraised at 10 billion dollars. That gives you a net worth of 10 billion. But that does not mean you have a lot of cash

-- In fact it’s possible to be worth billions, but not be able to pay your rent

-- And the one thing about the race for the Presidency is that it takes a lot of CASH

-- Not net worth. Cash. Cash. Cash

-- We have yet to see Trump spend much on building an organization, which. Is critical to getting votes. We have yet to see that he has raised money from supporters.

-- After all who feels the need to donate money to a guy who says he is worth 10 billion dollars?

In a subsequent Cyber Dust session, Cuban followed up by writing that part of him hopes Trump becomes president just for the comedic potential:

As the Dallas Morning News also cited, Cuban and Trump have a history of dissing each other.
