But already this year, the value of Bitcoin and other cryptocurrencies dropped after the Federal Reserve took a more hawkish stance on its monetary policy, scaling back on the amount of bonds it holds and indicating that it'll raise interest rates. Cryptocurrencies, which operate outside of central banks and government organizations, certainly aren't impervious to the shocks of the global banking system and marketplace. In addition to their market risk, cryptocurrencies remain highly controversial because critics point out they aren't tied to a regulated central bank or a sovereign institution, which makes them much harder or even impossible to regulate.

That means cryptocurrencies and Bitcoin, in particular, have already been seized on by those who want to use them for money laundering, buying illegal goods or circumventing capital controls. But despite such controversies, crypto's popularity and use are growing rapidly as of late, to the point that it's well on its way to becoming a significant disruptor to the world economy in the next few years. As a result, many corporations, financial institutions and investors -- many with a big case of FOMO -- are trying to calculate the potential financial rewards of getting involved with crypto.

Credit their popularity to the fact that they're stable in value and that they're capable of supporting more transparent and efficient value transfers than legacy payment networks. Avivah Litan, distinguished analyst and VP at Gartner, who also co-authored its report, Predicts Prepare for Blockchain-Based Digital Disruption , told ZDNet that you'll see cryptocurrencies being used for retail payments in about three to five years.

Now and in the next couple of years, you'll see a lot of interest and adoption of cryptocurrency by investors as an investment tool, namely as a hedge against inflation and as an alternative to gold. However, it remains an extremely volatile investment. Despite this, there's little sign that investors or companies are backing down from the potential reward crypto has to offer. That's not just down to speculating on the price of cryptocurrencies.

Some investors and companies are also interested in crypto to get into decentralized finance or DeFi. Banks have to serve these companies, becoming digital asset custodians, and it's a global phenomenon, not just in the US. Governments throughout the world are also opening up to blockchain and crypto now. See also: Cryptocurrency scams pose largest threat to investors.

Clamping down on crypto scams and misuse will be key to gaining mainstream legitimacy. Among the more recent types of scams are so-called 'rug pulls' in which developers build crypto projects that appear legitimate only to then abscond with investors' money, never to be seen again. But with the dramatic growth of cryptocurrency use in , there is encouraging news: illicit activity is at its all-time low.

Only 0. Another benefit blockchain is having with regards to the future of money is in customer loyalty rewards programs. For years, loyalty and rewards programs were met with hostility by customers for being inflexible with customers' needs. Sign up thinking you can redeem points for a product or a discount on a service, and you're met with conditions and constraints about how and when to spend those points.

The frustration and disappointment ultimately lead to loss of revenue and customers. As online shopping becomes the preferred choice for consumers, retail businesses are adopting blockchain technology to help them track and manage transactions in hopes of elevating the user experience by providing more dimension, flexibility, clarity and transparency.

Perhaps the most technically innovative, financially lucrative, and most misunderstood blockchain-based crypto asset is the Non-Fungible Token, or NFT. Like a one-of-a-kind piece of artwork valued for a large amount of money, such as a painting in the analog world, NFTs are their digital counterpart and can be anything -- from a tweet to a video clip to physical property such as real estate. It all comes down to tokenizing the asset in the digital landscape, be it an algorithm or code for a video or JPEG, to the digitized paperwork of the deed to a piece of land.

Whatever it is, it's unique and can be identified as such in the virtual world. Cryptocurrencies, however, are fungible in that another cryptocurrency of equal value can replace them. NFTs are one of the more creative waves of the future of money.

Although most people still see very little value in the existence of NFTs, by , Gartner predicts that NFT gamification, or GameFi — which takes video game elements such as point scoring and applies blockchain tech, so users can trade or swap game assets — will have the ability to propel an enterprise into the top 10 of highest value companies. What's more, NFTs are expected to become a more powerful digital marketing tool in the coming years and that more traditional enterprises may 'auction' limited digital use rights for some of their unique intellectual digital property, according to Gartner's report.

And this is not just in video games but also in sports, financial services, social media and manufacturing. There's plenty of debate about what the 'metaverse', the next-generation virtual reality-powered version of the Web, might look like.

Although not owned by any one company — Google, Microsoft, and Samsung are also participating with Facebook with their involvement in the XR Association — Facebook has placed the biggest stake in this virtual land with an elaborate marketing campaign, which included renaming itself, Meta. It claims that its concept of this digital marketplace will be "a set of virtual spaces where you can create and explore with other people who aren't in the same physical space as you.

See also: CIO priorities: 10 challenges to tackle in Where there is plenty of skepticism , fear and downright hostility toward the metaverse concept, many argue that it will be the place where retail shopping and cryptocurrency converge. Gartner's Litan believes that while businesses start making money in DeFi, consumers in a few years will notice the effects of spending digital currencies through the metaverse.

I think consumers will start feeling the crypto world through Facebook, the metaverse and play-to-earn games," Litan said. Elyashiv equates the metaverse of today with where we were with the Web in the s when it took seemingly forever to download an email attachment. Elyashiv believes the issue with the metaverse is that a lot of technology needs to evolve to make it smooth and accessible for everybody, and it will evolve exponentially so that the early years will feel very slow.

Great course, a very broad and in-depth overview of concepts surrounding cryptocurrencies and Bitcoin in particular. Would be great to have an update of course; perhaps once the ICO craze is over?

I've gained a strong knowledge of Bitcoin's architecture but wish this course was updated to include the developments of the last two years. A few lectures on alt-coins would have been useful as well. I find this course prepared very well. There are many perspectives and this course does not concentrate on the technology only. I find this course very helpful.

The level is more then just beginner. I enjoyed the lecture series. As many have stated previously, I do think that the assignments assume a sizeable amount of technological knowledge that is not necessarily cohesive with the lectures.

Basically, the cryptographic equation is throwing a pumpkin the block off a building and telling you what the splatter pattern looked like.

The only way users can match the splatter pattern — and send the block — is to hurl a bunch of pumpkins off a building themselves. Every computer in the network adds the new block to its copy of the digital ledger, and the process continues. Although bitcoin was created to avoid centralized banking and government money, the technology can be used as a national, centrally banked currency. In 50 years, Yermack says, cryptocurrencies could be used as national currencies.

Those who are hopeful about the rise of bitcoin may have noticed its popularity in countries like Zimbabwe and Venezuela, where it is being used as a major means of exchange when government-issued currencies have failed because of hyperinflation. Bitcoin and other means of exchange have become popular in these countries because transactions can be performed on cell phones, and their value is more stable than the hyper-inflated national currency. But others believe that bitcoin is too riddled with problems to be the cryptocurrency upon which the future is built.

Issues of privacy also stop it from becoming the future of money, says Phillipa Ryan , commercial equity lawyer and lecturer at the University of Technology Sydney. Not enough in that transactions are actually traceable by pseudonym.

Its value also fluctuates too much to provide a stable, functional currency. Unlike traditional currencies, which have a value that is set by the central banking system, the value of bitcoin is driven by speculation about its worth like a stock, says Yermack. One bitcoin, on the other hand, could be worth a candy bar one day, a car the day after, then next to nothing the day after that. James says that, based on the historical precedents he studies, bitcoin looks like the highly unstable private currencies created in Eastern Europe after the First World War.

When speculation about the value of bitcoin is substantially more than its worth in the real world, bitcoin will burst, like the stock market crashed. In the meantime, bitcoin will remain as a grand test of the blockchain technology, says Ryan. Bitcoin offers something groundbreaking, and a growing number of national banks, including the Federal Reserve, are interested in using blockchain technology to power a centralized national currency.

Most experts agree that, in the future, countries will turn to cryptocurrency, as money is already moving from the physical to the digital realm. So a method that secures digital transactions is a necessary investment, and the blockchain technology used in cryptocurrencies is a top contender. Based on the issues of cybersecurity looming ahead, Ryan thinks that the blockchain will be the technology to transform the money of the future. Blockchain could make its way into the mainstream in two primary different ways.

One option is to switch from physical to digital currency. A dollar would still be a dollar, but transactions would use blockchain to make them more secure. The second way would be to move your bank account from something like CitiBank and transform it into an account in the Federal Reserve itself. Some institutions are beginning to try it. The Bank of England is working to create its own cryptocurrency and has created an experimental cryptocurrency framework called RSCoin that would use a centralized system.

To go crypto, the Bank of England would create digital money as if it was printing physical notes. For example, in , there were Since the value of the British pound is based on how many are in circulation, exchanging a physical note for a digital one has no economic significance — that is, a pound is still a pound, says Yermack. Like bitcoin, RSCoin would use a public ledger and the cryptographic system to distribute money.

In their paper on the RSCoin model, the authors write that a cryptocurrency backed by a national bank should help make cryptocurrency usable on a larger scale, since the central bank could employ other institutions to do the computations to verify transactions. And with national cryptocurrencies, it will be more difficult to conduct illegal activity.
