Fiat/BTC funds used for the "Get Paid" wallet tab.

Something I just happened to think of today when I was out for my walk: where do the funds we currently use to cash out to fiat and BTC come from? Was that from the initial fundraising? If so, where will the funds to replenish that bank/pot come from? Will that solely rely on people buying Lino from the dapps or is there some other kind of fundraising needed... or will we eventually need (no, don't say it Rob!)... ads? Also along those lines, is there some kind of system expected to publish information on Lino's available balance to cash out those points with?

I'm sure these things are probably addressed to some degree by the whitepaper, but I'm hoping this post can still be addressed once this information is known and released to the public.
