He's claiming to have more than enough hashing power than needed to 51% DGC. Will be interesting to see what happens - but I see exchanges going bust very quickly with this going on!
I'm all for it. I support his position but not for his reason. His actions will weed out the weaker coins and developers. Hazard coins will be wiped out because the developers are not skilled enough to manage their coins. The rest will implement merge mining to secure their networks. DGC and ARG are already implementing this. So all in all he's making the alt network better.
He probably thinks that the recent LTC weakness is due to the alts and it clueless that its ASIC owners dumping BTC/LTC to get their hardware investment back.
