That's wrong, the same attack (and others artforz is aware of) are possible with Bitcoin, at relatively little expense. The reason artforz decided to attack SolidCoin was due to his own ego, dislike for me and the project and the fact he is malicious in nature. Artforz "warning" me is also a bit of a joke, he sent me about 5 lines of text, mainly talking about 51% attacks. I simply said the "extra" 51% attacks are irrelevant because at 51% you're dead anyhow. This somehow get's translated into me "fobbing him off" and "not listening" . It's a bit of a joke.
