Geez, $15.24 per coin sounds kinda expensive for a starter, but I do believe that Zcash is going to be big.
According to the article this also includes an equal stake in the company. With this in mind the price per coin is infact lower, depending on how one values a stake in Zcash corp.
Why mentioning the "value" of one coin... this sounds like putting a price-tag on it for me. Especially with their over-time-mine ( the 10% ) it makes NO sense to put that tag on it.
There was a lot of discussion that the coins were practically gifted to investors because their investment would be negligible compared to the coins received. This clears up that investors did take some risks on the price.
