Why Should I keep Playing on Ignition?

When I look at my rewards page, I see that I am Diamond Level and I’ve earned the maximum number of Ignition Miles possible:

4,572,204 Lifetime miles
Additional requirements needed to reach next level

When I click on "Discover Diamond Level VIP Advantages, site displays the following:

Exchange 1000 Ignition Miles for $ 1.00
This is an exclusive invite-only level.

How much more money do I have to spend to be considered for “Diamond VIP Level”? What’s the benefit? There doesn’t appear to be any different perks associated with this unobtainable level. I already get $1.00 for 100 ignition miles… What is else is there?

I just became hosted. And I got a 500$ point drop today… so it may be worth it lol
