Elixir is one of my coins in the portfolio along with $Onion. Honestly I do not know $100 achievable or not but between $20 and $30 on a working product for Elixir should be good. Also need to know will it work like JustGiving and Funding Circle.
In my opinion they should use $Elix as escrow (guarantee) and launch another token with higher circulation on top for transactions.
