What is the difference between Nxt and Emunie ?
The main point is that EMU has no closed supply of coins unlike all the other coins, but uses an elastic algorithm to create and destroy coins based on the market while employing mechanisms to stabilise the price somewhat to avoid the volatility we see in BTC and 1.gen alts. Thus EMU is not deflationary in nature and to a certain extent solves the hoarding problem. However, if it was purely inflationary there would be no ROI. To compensate for this each time new EMU are created for new buyers, the equivalent amount of EMU will be created and split between balance holders as interest and hatchers as reward for network service.
The combined effect is a 2. gen coin that will function as a usable currency from the start instead of becoming another commodity/speculation object.
