Honestly i am finding it hard to clearly understand your question,but if i get you correctly i think what you are asking is that how do the price movement on the cryptocurrency market occur and how are the market capitalization determined....

well let me first of all start with how the market capitalization is determined,market capitalization is a combination of the total number of units of a cryptocurrency sold multiplied by the price of the cryptocurrency...

for example if total of 1000000steem was sold and its price is 2$ then it means the market capitalization at that moment will be $2000000...

now let me talk about what determines the price movement on the cryptocurrency market,the price movement is not a magic and it is determined by buying and selling that happens on the cryptocurrency market,demand and supply is a usual factor that determines how the price of the cryptocurrency will behave on the market

When there is an increase in demand and less supply then of course the price of that cryptocurrency will be forced to go higher and when there is a decrease in demand and high supply then obviously the price of that cryptocurrency will be forced to go down,so the trading activities happening on the cryptocurrency market is what determines the price movement happening on the cryptocurrency market....
