Wallet upgrade beyond 500?

[Maldito]

Is there a wallet upgrade beyond 500? If not, how can I get money to buy more expensive stuff?
I noticed that I have 530 / 500, so I'm wondering if there's no limit but there's a lose money past the limit on death mechanic or something.

Thanks for the help!

There is! Give the dragon some crystals

Yeah, dang it. I ended up figuring it out.

Because the first Dragon reward was money, I thought I was just able to exchange crystals for money, instead of getting different rewards.

...Thats funny, I made the same mistake. The money reward is a bit misleading.
