hi nhirsch,
yes you are right there is a lot of confusion about eBTC old eBTC new and this was really not well organised at the token swap.
But it is not true that the token swap was announced 1 week before swapping. It was announced three weeks long on a lot of social channels (twitter, facebook, homepage, telegram, bitcointalk). My opinion is that if i invest in a new token i have to watch it, especially in the first month when such a project is growing up. I'm sorry for you. But this is definetly not a scam.
Follwing their telegram channel there is now a young team of around 15 people and some more volunteers working on the development. And they give their best. So don't call it a scam.
