Market Cap is really not the best way to measure a "coins" value, personally i think it should be based on transactional volume within its respective chain.

The number of coins is not the issue, its the coins without a finite supply, doesn't really matter if the coin needs to be split (.000003) or there is enough supply for one to be worth .3... The biggest piece of the value is the amount of liquidity in the system, need enough value for everyone to transact on a day to day basis. Now if the supply is not limited and someone has the ability to inject additional "coins", well just take a look at fiat.
