Bitcoin is NOT a Ponzi scheme!
It is a currency competing for dominance! It will REPLACE the dollar! Thus, all dollars are converted into bitcoin. The more dollars converted to bitcoin the value of bitcoin goes up, because bitcoin is NON INFLATIONARY!!
You are wrong. Bitcoin is a number. Number is not a currency but mathematical object. A currency is legally enforceable instrument which originated from loan contracts in a specific country.
Bitcoin's inherent value comes from the technology. The internet was about as useful as bitcoin is now before people realized the potential and it was widely adopted. Ideologues will never care about the current fiat value of Bitcoin. It's the potential to bring economic slavery to its knees.
