Still no response from the devs for coin swapping which makes me worried, but I did some math based on previous discussions about coin rewards.

I made an assumption of masternode rewards for the interested ones as below:

According to the X11 algorithm, generated coins per block can be calculated by 2222222/(((PoS_Diff+2600)/9)^2)

If we take block number 11047 as reference (PoS_Diff was 16789.290, can be checked from here: http://193.70.109.114:5003/)

Number of PoS coins generated per block is 2222222/(((PoS_Diff+2600)/9)^2)=0.479 coins/block

According to the coin specifications, Masternode reward is 50% of the PoS coins which makes 0.479*0.50= 0.239 coins/block

XCXT block time is 1.5 minutes which corresponds to 960 blocks for a day.

Taking our difficulty assumption as reference (actually it is changing dynamically), Masternodes in total will get 960*0.239=229 coins for a day.

This amount will be distributed among MNs. According to the number of MNs, each of them can get the following coins based on our assumption:
( Let's also calculate USD value based on BTC=4000$ and XCXT=0.00001500 BTC (0.06$) )
 
10     MNs = 22.9  coins/day for 1MN (1.37     $/day, 41    $/month)
100   MNs = 2.29  coins/day for 1MN (0.137   $/day,  4.1   $/month)
1000 MNs = 0.229 coins/day for 1MN (0.0137 $/day,  0.41  $/month)

EDIT:
*MN reward corrected as 50% thanks to azkashtan.
*Specifications are based on first page announcement (if devs correct them, i will update the calculations)
