There were hardly any miners mining this coin, especially when it was cpu only. I stumbled on vertcoin 2 days after the gpu miner was released and have been mining it from then on. The diff was at ~2..4 when i got in.
Sure, the diff must have been low at the start, and there were only a handfull of miners, and the diff retarget was slow, giving those miners a FAIR advantage. Anyone could have stepped in at that time. If you were not smart enough to get in then (like i didn't) and did not have the vision to do so then you call the early miners insta-miners? What about the early bitcoin and litecoin miners? Insta-miners too?
And why hidden? All coins were mined after the release no? Hidden insta-mine = mine before release, obviously that hasn't happened to vertcoin.
This is just someone pissed at not getting in early by ignoring the coin at the release.
