This one's difficutly went up from the interest at launch from what I see. You have proof of the instamine? One thing for sure it isn't premined, and if it was created from Wolongs Dev, well my hats off to him. For once he did something right!
Yeah it was like 20 difficulty in an hour. There was nobody who got any benefit to any sort of instamine on this one. Just scroll back to whatever page and you'll see all the "OMG already xx difficulty!" posts shortly after launch. Then it settled at ~40 for about a day. Obviously it's far better to mine at that then ~150, but it's not a HUGE advantage to the early adopter. I was expecting to mine 100,000 coins easy, with a target of 150,000-200,000 by the time this was finished. At the rate things are going, I may not even reach 100,000 mined so I am resorting to buying (earlier today and now as well) more coins.
I concur exactly with blade87. Was in from the very start, got lucky solo twice and have now resorted to buying. It seemed fair to me from the outset and I thought that well before I was in any meaningful way invested in it.
