All of them, crypto's are pump and dump but the good thing about it you can choose a lot of it.
But I will still prefer to bitcoin and there's no way to say that Ethereum is a scam.
And it's also promising as Vladimir Putin is showing it's interest to use it to his country and wants to meet eth's creator.
Initial distribution was fake deal, all it ethereum still under control same group of people (gang).
Also this:
1. Fake market capitalisation.
2. Market manipulation.
3. Hyperinflation.
4. Running off with your money - soon. Vitalik have no roots and will do it easy.
