ZClassic is a fork of the popular ZCash currency. The biggest draw of this fork is that the 20% founders reward incentive was removed, as some in the community found this to be unfair, so they forked into a new coin.
Potential investors should be aware that all development of this coin has stopped. That means that there will be no more updates for this asset, and those who would look to buy it should be very careful that they are not left holding a useless asset.
The ZClassic team has stated that the nodes for the network and the electrum wallet servers will be shut down, but the community is free to host their own nodes. They have also stated that they will be taking "applications" for teams interested in developing the coin further, but thus far no such teams have approached them, and that leaves any Zclassic investment standing on shaky ground.
Investors who are looking to buy Zclassic can do so on several exchanges. This includes a high volume option and a couple others that don't require verification if you are a privacy advocate or you live in a country which exchanges make difficult to register an account. Bitcoin is the most viable trading pair here as it carries the most volume.
The best way to store your ZCL is by using the official wallet. You can download this from the coin's website. They have made installation packages available for Windows, Linux, and Mac. Or, if you prefer there are also paper, web, and mobile wallet options available for you to use. In any case, be sure that you create a strong encryption password and that you make a backup of your wallet file in a safe place.
