Why is the Zcash to BTC value always relatively stable since its inception, but every other crypto I look up has its gold line (in coinmarketcap.com) wildly swinging all over the place? Also, the market cap is always way higher than the other two lines.
It might be because since its the first week and might not be a stable as you thought it might. The trend will definitely stable and will always have highs and lows.
