"Money is a medium of exchange for wealth, it is not a store of wealth."
Disagree. To be a medium of exchange, money must have "holding" value (because money does not circulate, but simply switches holders: http://blog.oleganza.com/post/43378777734/on-circulation-of-...). The liquidity of money is in how many people want to hold it in their cash balances. The more people want it - the bigger value of the total supply (regardless if it's slowly shrinking or growing). The more and longer people want to hold cash, the bigger liquidity - the more "wealth" you can reliably "move" from one person to another. E.g. Bitcoin valuation is pretty small right now, so people can't use Bitcoin (yet) to make multi-billion purchases. Because to make multi-billion purchase one of the parties must hold billions and another must be willing to hold billions (and then find others to who give them if they need in the future).
So the money to be a good liquid medium of exchange must be a good store of wealth. And the more wealth it is "storing", the better medium of exchange it is.
