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

MonaCoin Market Capitalization in USD = Number of MONA in supply X Price of one MonaCoin in USD

Since the price of MonaCoin is highly volatile you can see the market cap going up and down a lot.

So you can say that it's not simple to predict the market cap of MonaCoin or predict the price of MonaCoin.
