Making money with zero investment

Can it be done?
Steemit was created as a way to make 💰 can this be done without investment.
Many people have tried and given up
Many people are making money
Having a look around it seems as though it is important to invest in order to make money.
I have made $1+ in about a month so you can make money no one mentioned how much
My mission is to make money without investment so I will not put any money on the account and see how I grow naturally
Will it work only one way to find out 😊
