VIII Watch the video and choose the correct option to complete the sentences.

An exchange-traded fund is a basket of financial secured/securities/securely that tracks certain assets, like an index or a sector. They can be traded on stock exchanges, just like a share in a company. In 2021, the Securities and Exchange Commission gave the green light to the first U.S. bitcoin-linked ETF. And bitcoin bulls hope there will be more ETFs backing/tracks/tracking the cryptocurrency in the future.

There's even a country where bitcoin is considered legal attention/legal retention/ legal tender, with El Salvador enacting a law requiring businesses to accept  bitcoin as payment in September 2021. Experts say such moves will pave the way for further acceptance/accepts/acceptably of cryptocurrencies. The first ever real-world bitcoin transaction/fraction/transacted was   believed to have happened in 2010 when a Florida-based man exchanged some for two prizes/completes/pizzas. But despite all the traction bitcoin has gained, there are still some big hurdles it needs to overcome. For one, bitcoin remains incredibly volatility/violated/volatile. It's been known to increase or decrease over 10% in a single day. And critics argue these enormous price fluctuations have made bitcoin less effective as a means of paid/payment/payable. Another big use of bitcoin in its infancy was crime.

Tom told me more. “Most people associated bitcoin with the Silk Road, which was a darknet marketplace/marketable/marketed where you could buy drugs or hacking tools or  you know, fake IDs. And so we looked for a solution to that problem. And what we realized was that, you know, Bitcoin is actually highly traceable/tractable/tracings. And that you can identify transactions associated with criminal activity.”

Over the years, bitcoin’s refutable/reputation/reputable has morphed from a protest against the financial establishment to an investment that’s increasingly being embraced by Wall Street. And the portion of crypto that's being used for illegallyillegal/legal activity appears to be on the decline, with data showing only 0.15% of bitcoin  transactions in 2021 were related to crime.

 Still, with bitcoin prices at historic highs, it's become a much more lucrative asset for criminality/criminally/criminals to exploit. In May 2021, hackers attacked a U.S. oil pipeline system in a ransomware attack that took the critically/criticize/critical energy infrastructure offline.

So last year, a new ransomware group called DarkSide emerged. And they perpetrated one particularly high-profile attack against a company called Colonial Pipeline, which is responsible for much of the fuel transport infrastructure/restructure/instructor on the East Coast of the United States. And so, this attack basically crippled that company, and meant that people couldn’t fuelled/refuel/prepay their cars.

Colonial paid DarkSide, the hacking group behind the attack, nearly $5 million in  bitcoin to restore recess/access/accept to its systems. But they weren't completely successful. A month later, U.S. authorities seized $2.3 million of the haul, after locating one of DarkSide's virtual currency wallets/warrant/fillets.
