(fiat)... inflation is minimal.
Our modern financial system(federal reserve) is a pretty darn amazing invention. Money is never wasted.

BitCoin alternatives
There are plenty of alternatives to BitCoin.
You can use regular money on your grid by way of PayPal and PayPal Micropayments. These modules are widely available for OpenSim and many hosting companies will set you up for little or no extra cost.
You can use the OMC currency from Virwox — which also supports BitCoin trading, if you want your customers to have the option to use BitCoin in some capacity.
And you can issue your own currency. That has some legal implications as well (see yesterday’s article Virtual Currency 101), and you have to be careful about how your set up your currency, but if you do it right you get to keep all the money you make from selling your currency in addition to providing a fun, low-cost way for your users to spend money in-world.
Hosting companies Dreamland Metaverse and TalentRaspel specialize in setting up custom virtual currencies for private grids — and the Website infrastructure needed to manage them. And the currency modules are also available, if you have the technical skills to set it up on your own.
