Query: The coin that never sleeps. The privacy preserving usage of Bitcoin in a
  longitudinal analysis as a speculative asset   Bitcoin is the first and undoubtedly most successful cryptocurrecny to date
with a market capitalization of more than 100 billion dollars. Today, Bitcoin
has more than 100,000 supporting merchants and more than 3 million active
users. Besides the trust it enjoys among people, Bitcoin lacks of a basic
feature a substitute currency must have: stability of value. Hence, although
the use of Bitcoin as a mean of payment is relative low, yet the wild ups and
downs of its value lure investors to use it as useful asset to yield a trading
profit. In this study, we explore this exact nature of Bitcoin aiming to shed
light in the newly emerged and rapid growing marketplace of cryptocurencies and
compare the investmet landscape and patterns with the most popular traditional
stock market of Dow Jones. Our results show that most of Bitcoin addresses are
used in the correct fashion to preserve security and privacy of the
transactions and that the 24/7 open market of Bitcoin is not affected by any
political incidents of the offline world, in contrary with the traditional
stock markets. Also, it seems that there are specific longitudes that lead the
cryptocurrency in terms of bulk of transactions, but there is not the same
correlation with the volume of the coins being transferred.
