By Paul Hirsch and Andrew Harding BBC Sport Bitcoin has been a hot topic in the financial markets this week.

This week, some of the biggest players in the digital currency space are looking to cash in on the trend.

Bitcoin price and its value are also at the heart of the global financial system.

Bitcoin is a digital currency that can be used to buy or sell goods and services using a set of online virtual currencies.

Bitcoin, the most widely-used digital currency, is now worth about $US3.3 billion ($4.4 billion) after surging to $US2.6 billion in late September.

It has gained more than 50% since the beginning of the year.

It was worth $US8,700 on the first trading day in July, according to CoinDesk.

A Bitcoin “investment” involves buying and selling digital currency for a small investment.

These are called bitcoins, and they can be exchanged for real money or used to pay for goods and service.

It is a currency that has value because of the cryptography it uses to prevent the transfer of funds between people, companies and even governments.

There are also other ways to make money out of bitcoin.

For instance, it can be sold to investors on the exchange market, which allows them to exchange their bitcoin for money.

This is how Mt Gox collapsed in March.

The company’s website was hacked, leaving more than 80,000 customers out of pocket.

Some of these customers have sued Mt Goy for unpaid wages, lost wages and other damages.

The exchange market is one of the few ways people can invest in bitcoins.

The value of the digital currencies has fluctuated since the collapse of Mt Goya, a virtual currency exchange in 2009, but the trend has been upward since the start of this year.

The price of bitcoins has surged since the Mt Gollins collapse, according the CoinDesk Bitcoin Price Index (BPI), which tracks the price of Bitcoin.

In November last year, Bitcoin’s price fell below $US1,200 and then recovered.

Bitcoin has also gained more in the past week as it has risen from around $US700 a year ago to its current price of about $1,700.

The rise in bitcoin prices is also linked to the rise of Bitcoin Cash, a currency created by a group of developers who are using a fork of Bitcoin to make the currency more valuable.

A new “fork” has created Bitcoin Cash with more valuable features, including a new block size limit and support for multiple currencies.

The Bitcoin Cash fork was created by the developers who were the first to successfully fork Bitcoin and create Bitcoin Cash.

A number of other cryptocurrencies, including Ripple, Litecoin and Dogecoin, also came from the original Bitcoin fork.

The new fork also supports Segwit2x, a Segwit upgrade to increase the block size by 20%.

In this week’s Bitcoin price chart, the Bitcoin price is on a steady climb from around the $US500 mark to around $1.2 million in the last 24 hours.

Bitcoin and the future of the financial system Many investors are buying into bitcoin because it has gained in value.

Many are using it to invest in a variety of industries.

Bitcoin could become a main asset class for businesses, particularly in the US.

The Federal Reserve will hold its first meeting on Thursday and, if it is successful, will be the first time the central bank has directly tried to influence the financial world.

Many of the major US banks are also investing in the Bitcoin and blockchain technology.

This year, the US Federal Reserve is also expected to approve a “regulatory framework” that will help to develop the technology that will underpin the digital world.

It could be a boon for the financial industry as it allows banks to lend more effectively to consumers.

In the US, bitcoin’s value has been growing since it was first introduced by an anonymous hacker in 2011.

The hacker, Satoshi Nakamoto, has remained a mystery.

He was never identified as the creator, but he remains a key figure in the cryptocurrency community.

In December last year he was awarded a Nobel Prize in economics.

In July last year Bitcoin’s value rose to $9.5 billion.

Bitcoin was worth more than $US17.5 trillion before its collapse.

The currency is currently trading at $US400, down from more than a $US6 trillion peak at the end of 2014.

The cryptocurrency was designed to create a new financial system and it has created a new kind of financial services industry.

However, its growth has also brought new risks for investors.

The government has proposed new regulations for bitcoin, which could include regulation of exchanges.

This could create a bubble that could lead to a crash of the currency.

Bitcoin exchanges could be required to accept all currencies.

That could lead the currency to become worthless.

Another risk is that digital currencies could be abused by criminals and money launderers.

The most common way of laundering money is through bitcoin exchanges, which facilitate the transfer and settlement of illegal funds.
