You can check out above graph to see how the market cap of ZCoin has changed over time. The market cap value depends on the value of ZCoin on that particular day and number of ZCoin in supply at that day.

How is ZCoin Market Cap calculated?

The ZCoin Market cap is calculated using a simple formula. You can find it below:

ZCoin Market Capitalization in USD = Number of XZC in supply X Price of one ZCoin in USD

Since the price of ZCoin is highly volatile you can see the market cap going up and down a lot. Sometimes price and market cap are not linear to each other due to increase in the supply of coins in the market and stable or decrease in the price of the coin. So you can say that it's not simple to predict the market cap of ZCoin or predict the price of ZCoin.
