BEERDUST is a token which represents a Beer (or something similar), it is not meant to be traded. It is for easy exchange between friends, and should exclude the volatile part cryptos have.
For example: I pay for a friends beer, and in exchange he sends me a BEERDUST.
This must not be beer, but I think a beer is solid instrument to measure worth.
For example: A romanian beer costs in terms of euros way less than one in Germany, but for the people it would be pretty much the same in contrast to there income.
I hope you understand the idea behind this.
