Maybe. ZEC has been on the rise over the past months. If it continues as is, it may return to its original price levels since launch. This anon coin has a unique privacy feature which may turn out to become revolutionary once mainstream businesses and darknet markets start accepting it.

While ZCash could be considered as a good investment nowadays, other Zero Knowledge based cryptocurrencies can be ideal for investing in the long term too. ZClassic, Zcoin, Kurrent, and Komodo are all great coins with promising features. This last one called Komodo, has a GUI wallet with multicurrency support, as well as strong security with Bitcoin's hashrate making it a great sustainable cryptocurrency for the long term.

Nevertheless, only time will tell if ZEC's underlying technology would be put to great use or not. Just my thoughts.
