Warren Buffett is being generious with his praise of Bitcoin. Bitcoin is the tulip of the 21st century, destined to be obliterated by a better-implemented altcoin.
Oh my god, another florist. Please explain to me what has a flower to do with Bitcoin protocol? Can you send with your tulip on sunday at 1pm money from China to USA without middle-man within 1 hour almost for free? No? So stop comparing it...you guys with your tulips. If you really believe it is the same, why are you even here man/woman? Your comparison is just stupid, i am sorry to being rude.
The 'tulip' that most people refer to is the tulip bulb bubble, or tulip mania, that occurred in Europe. The peak of the bubble was in March 1637, with "some single tulip bulbs sold for more than 10 times the annual income of a skilled craftsman." The tulip bulb bubble and the potential Bitcoin bubble.
