There is no such thing as Nastymining shares.
I could care less about OgNasty's taxes, but what marlboroza posted does seem to contradict the above statement. This isn't my fight, and I can't say I ever understood what kind of business OgNasty does on the forum (though I've certainly heard about it through the drama), but how can he reconcile "no such thing as Nastymining shares" with:
This entitles the coin to a share of the NastyFans weekly Bitcoin distribution. Since it's private key is unknown by any individual, coins with their security hologram in tact can be traded with consideration to bitcoins held at the coin's address.
It really does sound like you'd be buying shares. Again, I'm not calling OgNasty a scammer and I know Vod is certainly no scammer but this sounds like a game of semantics.
