Can you clarify what you mean by scam? (note: I did not purchase any ether at the presale, and I do not own any of any cryptocurrency. I have no financial stake in any cryptocurrency succeeding. I am interested by the ideas in Ethereum though.)

Are you saying that it is a scam because you consider anything which has a presale to be a scam? (Or because of part of how the presale was set up, and what guarantees were or were not made at the time? Or because of the magnitude of the presale?) Or do you not believe that they will create what the have stated that they intend to create?(and believe that they have intentionally deceived others in this regard.) Or do you believe that what they create will be insufficiently secure due to network effects, and that that alone makes it a scam?

Or do you mean because of the proof of stake thing, and the nothing at stake problem? (In that case, note that they said that they are starting with proof of work, and I believe they also said that whether they actually do switch to proof of stake depends on what the users decide? I found vitalik's post about "weak subjectivity" to be fairly convincing. There seems to be a good faith belief that it does not contribute significantly to centralization, and as such, even if it is wrong, I don't think I would consider it to be a scam.)

Or some other reason which I have not considered or listed, of course.
