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

How is IslaCoin Market Cap calculated?

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

IslaCoin Market Capitalization in USD = Number of ISL in supply X Price of one IslaCoin in USD

Since the price of IslaCoin 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 IslaCoin or predict the price of IslaCoin.
