anyone with a penny can buy and use bitcoin. The price is completely irrelevant. If you own one dollar, you can buy one dollars worth of bitcoin. Same as when they were $0.06.
A too disproportional distribution of bitcoins may prevent a success on a mainstream scale. The bitcoin price can become very high without much use for ordinary transactions. Then bitcoin will remain largely an investment vehicle rather than being a general currency. That may be ok too if some other cryptocurrency can replace things like fiat credit/debit card payments. What I'm curious about is if bitcoin can become a general currency.
Early adoption of any successful enterprise is more profitable. That is just the way it works. The internet, stocks, start-ups. All favor early adoption. Those in early also take on much greater risk. It was not at all clear that bitcoin would work out and if their money had been lost would you be willing to share your money to cover their losses?
But will bitcoin become successful in terms of mainstream adoption? Bitcoin is already a huge success, as a proof of concept, not yet as a general currency able to replace fiat currencies. I wonder what will happen. It feels like a 50/50 chance that bitcoin will reach mainstream adoption. I think even big investors today sitting on trillions of dollars and zero bitcoins may be reluctant to invest in bitcoin because they have missed the innovators phase and don't want to make those who own bitcoins today become wealthier than themselves. So the big players may be planning to use another cryptocurrency to invest in.
Except that you will not be able to print for free. Things cost money and you will buy the software to print your hamburger then buy the stock material used to print it. Perhaps you will buy that stuff with bitcoin?
The point Ray Kurzweil has made is that even material things will become information technology with the price going down to zero. This will happen within just a few decades from now. In the near future things will of course cost money. It's not until perhaps in the 2030s when the price will significantly go down. But that's very soon, historically speaking.
