Once Reward a tron empty: What do u spend $$ on?

[SC00BYD00922]

Once your Reward a tron is empty and you max out on characters, what do you spend the money you earn on? 

what’s the point of winning $$ in Battle if you can’t spend it? 

Is there a convert cash to stars somewhere that I missed?   

Your thoughts?

The community has requested something like this many times, and got no response. The only thing you can spend them on is the XP machine.

Right now there's nothing. Sorry

@SC00BYD00922 You havent missed anything, many ppl are sitting on millions and cant do anything with them. We need exchange-o-tron 9000 to convert between cash, stars and bulbs.

@SC00BYD00922 Only the XP machine.

The only other exception to the XP Machine is buying Wizard in Rux’s shop IF you do not own him!  If you do, it costs 500,000 coins.
