Thank you for answer!

All these comes under crypto currencies so discussions on these are still debatable as their usage is banned or restricted by many governments across the globe. Coming to market cap for crypto currencies it is defined by both price and available quantity. Among all crypto currencies Bitcoin is the most popular currency as it is the first of its kind and is used by many so the available quantity is also more for Bitcoin thus market cap also. With changes in demand the price will fluctuate hence market cap.

As mentioned future price is based only on the equations of demand, if more users want to transact using particular crypto currency then that price will surge and vice versa.
