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

How is PostCoin Market Cap calculated?

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

PostCoin Market Capitalization in USD = Number of POST in supply X Price of one PostCoin in USD

Since the price of PostCoin 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 PostCoin or predict the price of PostCoin.
