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

How is PosEx Market Cap calculated?

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

PosEx Market Capitalization in USD = Number of PEX in supply X Price of one PosEx in USD

Since the price of PosEx 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 PosEx or predict the price of PosEx.
