Well you are true , people shoud be carefull, I put the signature of the project but I understand that I'm risking a lot because I'm not convinced of what I do, look very similar other fork project like ethereum classic visiono wich was a scam.
I think OP of Ethereum Beacon should more actively communicate with the community, here. Since the registered day, days ago, OP has posted only 2 posts. Last active on 1st August, but I do think he/she should more actively interact with Ethereum Beacon's supporters, potential investors. Keeping silently after creating threads (ANN, bounty) is not good way to attract investors.
I don't think so. In my opinion, the team is the same behind the Ethereum classic vision and site is suspended. Be careful about this project, they never send you any additional coin for giving away the private te keys.
