Reset Min for Total Bonus

What is the min # of times you have to reset in order to get every single possible bonus? That is 999 cap points, as well all ap points for gold, exp, tower buffs, etc. 

I know cap points depends on Onslaught floor and my level, so that is more subjective, so ballpark that part.

Do exp and gold cap at some point? If so, what is the max?

To get all the powers it takes 70 points I believe. The talent caps you will get regardless of your level and floor if you do that many resets, I did 58 resets and I have +11,000 to talent caps. As of currently there is no known cap on xp and gold bonuses, we have players at and above 200 resets that were still getting the 5% to both each reset.
