Agree. With the recent bear market, all you can do is buy coins at a cheap price and quickly sell them whenever prices rise a little. ZCash has seen a constant decline in its value ever since it launched as a cryptocurrency for the masses. Compared with its ATH in 2016, ZCash is still cheap and could become a bargain these days if it continues to grow in user adoption and development. By securing your coins now, you could effectively make some profit as ZCash grows into an ecosystem for fully private transactions.
The technology is there, but it will depend if the people adopts the cryptocurrency for usage in the mainstream world or not. ZCash could be a wonderful coin, but if it lacks marketing/promotion, then most people won't become aware of it, which will result in decreased usage over the long term. Hopefully, that won't be the case, as ZCash and other privacy coins gain momentum due to people's privacy concerns over popular cryptocurrencies such as Bitcoin and Ethereum. Just my thoughts
