As mentioned not all criteria need to be filled.
But a cryptocurrency need to have a blockchain, if not it's just a centralized object/code that can be copied and pasted several times.
That's not a cryptocurrency which OneCoin claim it is, so they are lying to investors openly.

So people who sign up aren't informed, because they are being fed lies and that's a scam.
You can read all you want on their page but when they are lying they are the ones who needs to be blamed.
