It is real, but its price is at the top of a crazy boom, and the price is bound to collapse soon. If you buy some, I would do it for purchases, and don't assume it will be a good investment. (Don't buy GBP either, as I'm sure the price will collapse there too this week. )
I was reading somewhere that Bitcoin is government propaganda. That the technology behind it is based entirely on government r&d such as the internet and military cryptography. Something like even with the transparent central database- blockchain where their transactions are recorded for eternity...everything about bitcoin is related to the state. I am however still in doubt if this is true?
