You can use a XDAG mining calculator @
http://b.xdagtalk.com/mic/miningWith 40 MH/s: Estimated coins per day: 8.324598822489 . With such less hashrate I would suggest you to join xdag.top pool with over 4 TH/s mining hash power.
4 TH/s out of 6.5 TH/s total nethash at one pool, such even distribution of hash power is a good sign for the community. also a good sign that this xdag.top pool doesn't even contribute to the community development fund either. pointing new miners to this pool is priceless for healthy community. good job /s
Community fund 1% has been donated from the first day of xdag.top online. It may have donated about 100000 XDAG. to 02-22 until the donation was cancelled.
I did not see any work done by the community and did not write xdag.top on xdag.org.
