From what I understand, ether doesn't exist yet. So this is probably a scam.
ok i'm selling ETH in the other thread too...
https://bitcointalk.org/index.php?topic=762079.0and i have to say... i dont think its a scam....
i meet one of the guys behind it at a bitcoin meetup.
Ether is a "Bitcoin 2.0" protocol ( you can code with it ) or at least its gana be when they finaly perfect it.
anyway... hero member "saying i really don't thing ETH is a scam coin..."
take it how you will.
I think people may be wondering because the ether genesis block will not even be created till next year

Maybe you should explain that you are trying to sell an IOU for future ether. and that since you can still keep a copy, you could get the future ether and keep the payment too ...
Fully agree with you, we can't say what will be the price when it will on market,
Buying this time is really very risky investment because we don't know when will it will live on market.
