Well I think Lithium is a scam for the following reasons:

No Escrow
No Source code
No Technical White paper
Anonymous dev with an inactive account for two years only to reappear for the ICO

If the dev is willing to use an escrow and only release funds after the  source code and the technical white paper has been made public and verified, I will drop my scam accusations. When I asked these questions, the dev conveniently ignored mine and other posts which had similar concerns.
