The Bitcoin: history and evolution 2/2

Acquiring bitcoins
Bitcoins can be bought and sold (ie. exchanged for real currency) to and from individuals or companies. Most known platforms like Bitstamp, Mt.Gox, Btc-e and BtcChina use a bid / ask system.
Today’s value is $461 US for 1 BTC, but this is subject to high fluctuation.
We have seen this exchange rate going from $5 in May 2012 to $1150 in December 2013.
Legality

The bitcoin, literally a coin made of bits, is a decentralized digital cryptocurrency created in 2009 by an anonymous developer known under the pseudonym Satoshi Nakamoto. Its symbol is BTC.

The bitcoin is very similar to gold. Only 21,000,000 Bitcoins will ever be created as only X amount of gold will ever be discovered on Earth. This is different from usual currencies where central banks can print money at their discretion. (suite…)
