This is not correct. A pyramid scheme is any system where existing users earn profits by getting new users in, while a Ponzi scheme is a specific type of pyramid scheme (usually masked as some different form of investment) which explicitly forces you to leave your money in the hands of the owner for a while, promising to get it back with lots of interests. When a Ponzi scheme can't get enough new funds in to cover payments due to existing members, the owner can and will disappear with the money; with our system, you simply stop getting new payments. If you already covered your initial investment and made a profit, there is no way you can lose that, because it will already be in your wallet. There is no collapse: in the worst case you will not earn anything for a while, but you will resume earning as soon as you get new members in.
True. But it's perfectly understandable that people want first to test the system with as little money as possible. This is why we created the 0.001 BTC Pyramid, which is obviously useless if you want to actually move money around.
There are no fees. We own the root address of each Pyramid and all our earnings come from that.
Oh, and of course some addresses are ours, we used them for testing before going online.
We couldn't actually invest anything even if we wanted to: when we join a Pyramid, we are just sending money from an address we own... to another address we own. At least until more new members get in
