Payment
Basically, the purpose of such a token is a coin that can be used to pay for goods and services. (Bitcoin, Litecoin)
There are thousands of tokens and altcoins and most of them promise that they will be used as money, and none of them actually gets used. Same goes for smart-cotracts - they only find use inside the crypto sphere and not in mainstream economy. So the "objective" value of almost any token is zero.
