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

How is TerraCoin Market Cap calculated?

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

TerraCoin Market Capitalization in USD = Number of TRC in supply X Price of one TerraCoin in USD

Since the price of TerraCoin 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 TerraCoin or predict the price of TerraCoin.
