There will be 21.4 million RAQs. RAQ follows the same distribution and halving cycle as Bitcoin (every 4 years).
The current block reward of 12.5 RAQ/block is divided as follows:
Miners (50%, 6.25 RAQ)
Masternodes (35%, 4.375 RAQ)
Development Fund (15%, 1.875 RAQ)
For more information about how we arrived at this new distribution and the development fund, please read this blog post.
