The digital currency that was once a fringe currency for the fringe of the economy has become a global phenomenon.

With more than $20bn worth of Bitcoins trading on exchanges, more than 70% of the world’s population is now using the digital currency to buy things online.

And the currency’s recent rise in price has put it in the sights of some of the biggest players in the digital economy.

For one, there is the US, which last week became the first country to regulate and control the virtual currency, after it became clear that US regulators were reluctant to go beyond the guidelines set out by the Treasury Department.

The move followed the resignation of US Treasury Secretary Steven Mnuchin, who led the Treasury’s digital currency task force.

In a statement, the US Treasury said that it was working with the Bitcoin Foundation to make sure that US financial institutions comply with US financial regulations.

The Bitcoin Foundation is an organisation that represents Bitcoin’s leading figures, including the founders and its chief executive officer, Gavin Andresen, and is a not-for-profit organisation.

It said that the foundation was also working with other groups in the US to help the government understand the economic benefits of Bitcoin, as well as to encourage the adoption of the digital money by businesses.

The US Treasury has not yet responded to a request for comment from the Financial Times.

In Australia, Bitcoin is still relatively new, but the currency has been gaining traction as a means of payment for goods and services online, as people look for ways to get around the cumbersome and slow payment systems that they use in countries like China.

And it has also caught on with investors.

In December, the Australian Government announced it would accept Bitcoin for GST payments, while a company called Coinsmart launched its own Bitcoin ATM to help people buy goods online using the cryptocurrency.

In June, an Australian government-backed company, called CryptoCoins, launched a bitcoin ATM in Melbourne, allowing people to buy and sell goods using the virtual currencies.

Bitcoin has gained a global following, and investors have been quick to bet on its potential as a payment system.

The digital asset has soared in value over the past year, and has recently surpassed the $1,000 mark.
