Difficulty changes every 3840 blocks (but looking at reducing this potentially)
Reward halves after 100k blocks
Really like Emperux's suggestion below - maybe I'll reward with a few coins too!
As a matter of fact, lets do it like this:
I am mining a shitload of XCOINS and have some to spare.
Any one of you who uploads some proof of action that will help further XCOIN to either get listed on an exchange or just gain a bigger audience will get a reward from me. The reward is determined by the magnitude of your action but will never be less than 5 coins.
Lets get to work & dont forget to post your wallet address!
No news on exchange yet. I don't know why the windows wallet says "bitcoin:" but the important part is the part after that which is your receiving address.
