Thanks for the advice, mate. Given that ZCash is sort of premined (due to the founder's reward), I don't think that it will rise that much in value over the long-term. There are other good coins out there which have adopted ZEC's underlying technology, with some added features. This Zencash you've mentioned by the way, looks interesting as it will make use of masternodes to further increase its privacy.

Combining Zero Knowledge Proofs along with masternodes is extremely ideal towards increasing user privacy in a safe and secure way. Better off, most altcoins which make use of ZEC's technology don't have a founder's reward, making the mining process a fair one. Which means that ZCash will have a hard time trying to compete with these coins, as they bring new and exciting features at a faster rate than the former. Only time will tell if ZEC can keep up with innovation and development over the long-term. Just my opinion
