“Bitcoin is a currency for kidnappers and so on... that is partly fraud and delusion."
Berkshire Hathaway’s Charlie Munger has said that Bitcoin is a "currency for kidnappers and so on... that is partly fraud and delusion.". He is obviously rights. He only “forget” to say that the USD is also used by kidnappers, and its value is also is partly fraud and delusion.
Money is all about trust. Therefore Bitcoin and every other alternative cryptocurrency is expression of distrust of the USD and the current central banking system.
