Most people only focus on Bitcoin, the digital currency.
But that is not the important point. The important point of Bitcoin is the blockchain, or the digital public ledger. By making accounts anonymous and public, Bitcoin replaces the role traditionally played by commercial banks in recording transactions. This is because each bank would keep its own private ledger of all transactions; Bitcoin stands this on its head by creating one public ledger which is anonymous, and makes it freely available for download.
Then, by limiting the amount of Bitcoin in circulation, and making that number public, Bitcoin plays a role traditionally played by central banks.
Basically, Bitcoin is not just a digital currency, but aims to replace the role banks play in the economy. It is no accident that it was announced right after the subprime mortgage crisis in 2008.
When you consider the amount of public anger at banks, it is easy to see that most people have not yet connected their anger at banks, to using Bitcoin as a possible alternative to the banks.
When that connection becomes public knowledge, then Bitcoin will become more popular.
And the banks and traditional economics will be in trouble.
Conclusion
I have come to the conclusion that the biggest problem for Bitcoin is that the people who use it go into too much detail about the technology, and don't know how to explain the principle behind Bitcoin.
When you drive a car, do you have to know how an internal combustion engine works? When you use a computer, do you need to know how computer memory works?
NO!
But the people who "explain" Bitcoin insist that you need to understand all those things. How did they become their own worst enemies?
