You're a disgusting criminal.
No alt chain can be a pyramid scheme anymore than bitcoin itself is. And by the way, if done honestly, there's nothing ethically wrong with authentic pyramid schemes either. They are just a form of abuse of people's ignorance to get their money with their consent, pretty much like religion. Disgusting, but not criminal at all.
You, on the other hand, attacked an innocent project that had done no harm to anyone. If bitcoin is discredited by alt chains - what is obviously false, but anyway - that's bitcoin's problem. That gives you no right to go own attacking people's projects just because you don't like them.
By endorsing pyramid schemes, you have lost all ethical credibility.

Did you read what I wrote entirely, or you stopped on your highlights? Right after, I call them "disgusting" (I highlighted up there). That pretty much means that I don't "endorse" it. They are just not criminal if everything is done consensually, if every party agrees.
Now, using somebody's resources in way that was not previously agreed upon, and plus, in an attack against someone that has done no harm, that's criminal, and way worse than pyramid schemes or religions.
I think you need to read up on what a pyramid scheme is. You seem to have to serious misconceptions about it. You also conflate the misrepresentation of facts with "peoples ignorance". According to that logic, Worldcom and Enron were not criminal, they just exploited the stock market's ignorance about the true state of their finances. No ethical problem at all right?
You also manage to say something is ethically ok and disgusting at the same time. This is convenient in that you may point to either to deflect criticism from any side.
Amway is not a pyramid scheme because if nobody else enters the system, it will not collapse. Pyramid schemes are non-sustainable business models that require new investors in order to fund payouts to existing ones.
