I love the idea of the moon for a strong privacy coin like Zcash but it is not going to be possible until the inflation rate drops down to somewhere that the market can handle. We will be under 4% after 2 more halvings so my napkin math says early to mid 2028. Prior to that frame ZEC holders are going to keep losing value as their coins get heavily diluted 
If you are interested in joining my proposal draft effort for campaigning a new ZIP (like this one which was abandoned before a vote) - For a responsible software update for the Zcash supply emission implementation, Please DM!
