Something I realized today:
What makes bitcoin USD any different from a ponzi games that we see in the gambling section?
In those games, you send your coins to someone and he holds it until someone else sends coins and then pays you, in the end no one sends him coins so payouts stop and the last guys who have coins in it don't get a payout.
How is bitcoin USD any different? You bought coin, someone buys them from you waiting for someone else to buy them and keeps going like that until no one buys them, or less people buy them so they end up losing their money.
You get USD for your work. You spend them to buy other people's goods and services. You put them in the bank, which immediately lends out 10x as much USD to others in the form of credit, fuelling asset bubbles and inflation, so your USD becomes worth less and less over time, so you end up losing your money.

Bitcoin is a decentralized ponzi scheme with no central authority. You f*** over each other by selling "bitcoins" to someone else who hopes someone else buys them from him.
USD is a centralized ponzi scheme with a central authority who f**** everyone over by printing more and more USD driving the value of your USD down, who hopes this will magically stimulate a debt-laden economy back to life and the lessons of history won't hold true this time.

You know I'm right.

Disclamer: I am not holding bitcoinsUSD any more.
I am taking my moneyBTC and leaving while I'm up.
Good luck.
