Currency is:
Medium of exchange
A unit of account
Portable
Durable
Divisible
Fungible ( interchangeable) meaning a unit dollar in my pocket is same as a unit dollar in your pocket.
With currency being the above listed, governments can print more and more of it thereby diluting the currency supply which results in transfer of wealth out of your pocket and bank account to the government and banking system.
Money is:
Medium of exchange
A unit of account
Portable
Durable
Divisible
Fungible
A store of value
Money being all the above as currency and in addition it is a store of value because it is limited in quantity, governments can not print it. Only Gold and Silver in the last 5000 years proofs to be money by maintaining their purchasing power. Lots of fiat currencies have all gone to zero.
