i think he want to say, wich is better betwen saving money at bank and spend it his money to buying something (gold, bitcoin etc.) for investment.
but saving money itself is like you investing your money at your country.
But I think you understood saving meaning wrongly. Saving money may help you when you need of money but it will not grow your money. Only in some countries, bank FD's will get some % interest but you need to consider inflation means over the time your savings value may go down. So you need to find a ways to increase your money either investing in any good products like gold or bitcoins or property.
