Unhealthy ? Depends whose health we are concerned about.
As above, most of these ETH Token sales offer little more than the right to re-sell your token. Similarly to how ICO's were public and now going private, the whole "buy solely so you can re-sell something with no intrinsic value" will likely seem less awesome later in 2018 - 2019.
Do we raise via Private or Public ? Have been asking myself the same question. Private can be quick and more certain, but only makes the wealthy wealthier.

I am still inclined to try to incorporate doing the hard yards and making opportunities available to individuals at home in their spare time, but this could take a lot more work for a lot less return.

Our Coin/Token will definitely NOT be offering only the right to re-sell the Coin. This could be attractive to a LOT of individuals to not need to go private, but maybe not. So will be going hard on a separate revenue generating project toward reducing the need to rely solely on ICO funds and/or be able to expense more on reaching the desired target audience instead of just whoever is willing to pay.

Does it matter who buys your Coin/Token or what they do with it? It does to us but should it?
