"You don't have to invest..........." - Man, I am not so sure about that. I might not have invested fiat here but a significant portion of my time goes on the platform here. Sure I want to buy more coins that I like - if I had the money, but that isn't the case. My time is what I have and that's what I am trying to use here.
I think time is an investment here and I am pretty sure a lot folks feel that way. In fact understanding that allows me to be more conscious of using it more efficiently here. Still the bottom line is that I am grateful that the platform allows me the opportunity to earn without spending fiat :-)
It is free and that is a fact. Still it requires an investment and that is how value is essentially generated here.
I agree ..
Actually time is also an investment.
Time is money
