hmm, yeah who knows. what makes you say zcash is a winner without doubts? (genuinely curious, clearly don't have full technical knowledge of either)
I think the market appreciate and understand more ZCash than Monero. The listing on Gemini might be showing this, also other important milestone covered by ZCash.
true, impossible to predict what the market chooses as it may or may not be the one that is technically better (not saying a particular one is, just that isnt a fool-proof method)
