I believe in the privacy potential of cryptocurrencies, even more so in Zcash. but I believe we need an entire ecosystem behind it (companies accepting Zcash), ways to spend coins using privacy, showing a sense for collecting Zcash and spending it when necessary.
my suggestion for Zcash is to enable the Zcash SDK to also serve as a Payment Gateway that can be integrated into ecommerce, and also to provide the creation of more simplified keys, such as an email, phone number, making things easier to use of public keys.
