After having been considered for a long time as the "currency of crime", bitcoin today interests more and more individuals and large banks. Electronic banking technological innovation seems to be on its way to conquering the Wall Street trading rooms. Bitcoin, created twelve years ago by one or a few anonymous developers, is about to convince the financial giants. “There is a very strong demand from customers. We have therefore put ourselves in a position to offer them,” says Andrea Tueni, head of market activities at Saxo Bank. For Andrea Tueni, large establishments are considering setting up teams specializing in cryptocurrency trading in their trading room, for their clients or for their own account. Global electric car giant Tesla has announced the purchase of $1.5 billion worth of bitcoins. These rallies support the course which continues to climb. Bitcoin has almost doubled in value since January 1, crossing the symbolic bar of 50,000 dollars (€41,200) in mid-February. One bitcoin is now worth the price of one kilo of gold, while all issued bitcoins are now worth over $1 trillion, more than the GDP of the Netherlands. Today, 100 million people around the world own bitcoins.
