1. A private decentralized network of people who pay a monthly fee to be part of the network. That fee doesn't need to be big ( i am already paying 50$ monthly to Netflix, Amazon, Spotify, and co. ) and I try to buy bitcoin every month from my monthly savings. (I am a late bloomer about bitcoin, but that is a different story)
Think about the money you'd have made had you invested 50$ a month in Bitcoin in the last few years. People who subscribe to a lot of things and pay a lot of fees usually don't make money. I don't need any of that. I don't subscribe to Amazon, Netflix, or anything else. I only pay my basic utility bills and Internet and spend what I can spare on Bitcoin. I'm trying to make money not spend them on subscriptions.
If only people could see how much they're spending on stupid things like a new version of a phone or a new car when their old one works perfectly fine.
Basically, our network assumes that more people will chip-in, then chip-out, so there will always be enough money in the pool to pay your amount in BTC back.
So it's like a social security fund.

They also expect more people will chip in and when it changes they ask government for help.
