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

How is MegaCoin Market Cap calculated?

MegaCoin Market Capitalization in USD = Number of MEC in supply X Price of one MegaCoin in USD

Since the price of MegaCoin 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 MegaCoin or predict the price of MegaCoin.
