Zcash just went into alpha testing. What does this mean? Nothing more than another "founder" trying to get rich in my opinion.
Remember for each one of these digital currencies that come online. The founder(s) usually have created a horde of coins for themselves (while testing, yeah right). I read an article (sorry I couldn't find the reference), where Satosha was rumored to have 100 million USD in bitcoins.
Don't be fooled. Similar to gold all of these "digital coins" have no value unless you attribute value to them. As soon as they have no population that will attribute value to them, they become useless.
