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

How is RChain Market Cap calculated?

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

RChain Market Capitalization in USD = Number of RHOC in supply X Price of one RChain in USD

Since the price of RChain 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 RChain or predict the price of RChain.
