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.
