There's no person or company that is paying out profits to investors.
This. In a Ponzi scheme, you pay money to someone, and they pay you a return. But that return that they pay you is actually stolen from someone else.
Bitcoin is just like a stock or a commodity. You buy a piece of a limited resource, or you're given a piece of that resource, and then you re-sell your piece later. If you pay $1000 for a Bitcoin and you're only able to re-sell it for $100, that might make it a bubble, but it doesn't make it a pyramid.
this. Another point: Transparency. In a Ponzi scheme investors do not really know, how the profit is made. The scammer tell people something and the investors have to trust the scammer. In Bitcoin: Open Source + properties of Bitcoin, which makes it valuable (fast, cheap, anonymous, etc.). Maybe some investors don't know about this and just invest, because they see the huge price raise, but this is their fault. The informations are there and easy accessible by everyone, in a ponzi scheme never.
You couldn't have said it better, the investors don't know how the profit is made.
I just pointed out to you in plain sight how it works, and you still can't see it. You are the dumb investor, getting scammed. Open source, cheap anonymous, blah blah blah. It's all the same regurgitated bullshit each time.
A currency = successful ponzi/pyramid.
Greed, #1 motivator.
I'm going to stop posting here, it's like arguing with a school kid, I probably am...
But it is not a ponzi scheme. Bitcoin is scarce and has its properties which people consider valuable. You can open a shop and double profits if every client paid in Bitcoin. Therefore the price for the product would decrease. And it is fast.
