Bitcoin

Blockchain refers to an expanding list of blocks where each one contains records. They are secured and linked to each other using cryptography. Within each block, you will find at the most basic level a hash of the previous block, timestamp, and the transaction data.

The origins of the blockchain technology are mysterious. Legend has it that Satoshi Nakamoto wrote the bitcoin white paper, developed bitcoin, and was behind the implementation and deployment of the original bitcoin.

Japanese men in their 30s and 40s are the biggest drivers of the bitcoin boom. 

Forty percent of bitcoin trading between October and November was conducted in yen, according to a Nikkei report.

Japanese investors, mostly men, came to dominate trading after regulators started to shut down cryptocurrency exchanges in China.

Bitcoin is trading at another record high on Thursday. The cryptocurrency is up 4.59% at $1853.55 a coin after Ulmart, Russia's largest online retailer, said it would begin accepting bitcoin, Cryptocoin News says.
