To a limited extent, they are also used for cross-border transfers. Blockchain Central to the appeal and functionality of Bitcoin and other cryptocurrencies is blockchain technology. As its name indicates, blockchain is essentially a set of connected blocks or an online ledger. Each block contains a set of transactions that have been independently verified by each member of the network. Every new block generated must be verified by each node before being confirmed, making it almost impossible to forge transaction histories.

The contents of the online ledger must be agreed upon by the entire network of an individual node, or computer maintaining a copy of the ledger. Experts say that blockchain technology can serve multiple industries, such as supply chains, and processes such as online voting and crowdfunding. JPM are testing the use of blockchain technology to lower transaction costs by streamlining payment processing.

An anonymous person called Satoshi Nakamoto invented it and introduced it to the world via a white paper in There are thousands of cryptocurrencies present in the market today. Each cryptocurrency claims to have a different function and specification. For example, Ethereum's ether markets itself as gas for the underlying smart contract platform.

Ripple's XRP is used by banks to facilitate transfers between different geographies. Bitcoin, which was made available to the public in , remains the most widely traded and covered cryptocurrency. Only 21 million bitcoins will ever exist.

In the wake of Bitcoin's success, many other cryptocurrencies, known as "altcoins," have been launched. Some of these are clones or forks of Bitcoin, while others are new currencies that were built from scratch. Are Cryptocurrencies Legal? Fiat currencies derive their authority from the government or monetary authorities. For example, each dollar bill is backstopped by the Federal Reserve. But cryptocurrencies are not backed by any public or private entities.

Therefore, it has been difficult to make a case for their legal status in different financial jurisdictions throughout the world. It doesn't help matters that cryptocurrencies have largely functioned outside most existing financial infrastructure. The legal status of cryptocurrencies has implications for their use in daily transactions and trading.

As of December , El Salvador was the only country in the world to allow Bitcoin as legal tender for monetary transactions. In the rest of the world, cryptocurrency regulation varies by jurisdiction. Japan's Payment Services Act defines Bitcoin as legal property.

Cryptocurrency exchanges operating in the country are subject to collect information about the customer and details relating to the wire transfer. China has banned cryptocurrency exchanges and mining within its borders. India was reported to be formulating a framework for cryptocurrencies in December.

Cryptocurrencies are legal in the European Union. Derivatives and other products that use cryptocurrencies will need to qualify as "financial instruments. Within the United States, the biggest and most sophisticated financial market in the world, crypto derivatives such as Bitcoin futures are available on the Chicago Mercantile Exchange.

This stance implies that cryptocurrency's legal status may become subject to regulation. Although cryptocurrencies are considered a form of money, the Internal Revenue Service IRS treats them as a financial asset or property. And, as with most other investments, if you reap capital gains in selling or trading cryptocurrencies, the government wants a piece of the profits. On May 20, , the U. How exactly the IRS would tax proceeds—as capital gains or ordinary income—depends on how long the taxpayer held the cryptocurrency.

Are Cryptocurrencies Safe Investments? Cryptocurrencies have attracted a reputation as unstable investments, due to high investor losses as a result of scams, hacks, and bugs. Although the underlying cryptography is generally secure, the technical complexity of using and storing crypto assets can be a major hazard to new users. In addition to the market risks associated with speculative assets, cryptocurrency investors should be aware of the following risks: User risk: Unlike traditional finance, there is no way to reverse or cancel a cryptocurrency transaction after it has already been sent.

By some estimates, about a fifth of all bitcoins are now inaccessible due to lost passwords or incorrect sending addresses. Regulatory risks: The regulatory status of some cryptocurrencies is still unclear, with many governments seeking to regulate them as securities, currencies, or both.

A sudden regulatory crackdown could make it difficult to sell cryptocurrencies, or cause a market-wide price drop. Counterparty risks: Many investors and merchants rely on exchanges or other custodians to store their cryptocurrency. Theft or loss by one of these third parties could result in the loss of one's entire investment. Management risks: Due to the lack of coherent regulations, there are few protections against deceptive or unethical management practices.

Many investors have lost large sums to management teams that failed to deliver a product. Programming risks: Many investment and lending platforms use automated smart contracts to control the movement of user deposits. An investor using one of these platforms assumes the risk that a bug or exploit in these programs could cause them to lose their investment. Market Manipulation: Market manipulation remains a substantial problem in the cryptocurrency space, and some exchanges have been accused of manipulating prices or trading against their customers.

Despite the speculative nature of the asset, some have been able to create substantial fortunes by taking on the risk of investing in early-stage cryptocurrencies. Advantages and Disadvantages of Cryptocurrency Cryptocurrencies were introduced with the intent to revolutionize financial infrastructure. As with every revolution, however, there are tradeoffs involved. At the current stage of development for cryptocurrencies, there are many differences between the theoretical ideal of a decentralized system with cryptocurrencies and its practical implementation.

Some advantages and disadvantages of cryptocurrencies are as follows. Advantages Cryptocurrencies represent a new, decentralized paradigm for money. In this system, centralized intermediaries, such as banks and monetary institutions, are not necessary to enforce trust and police transactions between two parties. Thus, a system with cryptocurrencies eliminates the possibility of a single point of failure, such as a large bank, setting off a cascade of crises around the world, such as the one that was triggered in by the failure of institutions in the United States.

Cryptocurrencies promise to make it easier to transfer funds directly between two parties, without the need for a trusted third party like a bank or a credit card company. Such decentralized transfers are secured by the use of public keys and private keys and different forms of incentive systems, such as proof of work or proof of stake. We will also refer to the parameters of functions in blue. When a term is particularly common in machine learning or data science, we will call it out with purple text, but only the first time it appears.

Whenever text is highlighted this way, that means it is a snippet of R code, which will usually be done to bring attention to specific parts of a longer piece of code. You can leave feedback on any content of either version of the tutorial, for example if something is not clearly explained, by highlighting any text and clicking on the button that says Annotate.

Please be aware that any feedback posted is publicly visible. At a high level, here are the steps we will be taking: Setup guide. Installation guide on getting the tools used installed on your machine. Explore data. What is the data we are working with? Prepare the data. Visualize the data.

Visualizing the data can be an effective way to understand relationships, trends and outliers before creating predictive models, and is generally useful for many different purposes. Definitely the most fun section! Make predictive models. Now we are ready to take the data available to us and use it to make predictive models that can be used to make predictions about future price movements using the latest data.

Evaluate the performance of the models. Before we can use the predictive models to make predictions on the latest data, we need to understand how well we expect them to perform, which is also essential in detecting issues. Are you a Bob, Hosung, or Jessica below? This section provides more information on how to proceed with this tutorial. Bob beginner : Bob is someone who understands the idea of predictive analytics at a high level and has heard of cryptocurrencies and is interested in learning more about both, but he has never used R.

Bob would want to opt for the more high-level version of this tutorial. Hosung intermediate : Hosung is a statistician who learned to use R 10 years ago. Hosung should start with the high-level version of this tutorial and later return to this version. Jessica should skim over the high-level version before moving onto the next section for the detailed tutorial. The term itself is defined in different ways: We can think of something as reproducible if anyone can run the exact same analysis and end up with our exact same results.

This is how the high-level version of the tutorial works. Depending on our definition, we may consider something reproducible if we can run the same analysis that is shown on a newer subset of the data without running into problems. This is how this version works, where the analysis done on your own computer would be between 1 and 12 hours newer than the one shown on this document. If you work with Excel files or any kind of data, there are tools to be aware of that can save you a lot of time and money.

If you do any kind of repeated manual process in Excel, chances are you would be better off creating a script that you can simply kick off to generate new results. Reproducibility is all about making the life of anyone who needs to run the analysis as simple as possible, including and especially for the author herself. When creating a one-time analysis, the tool used should be great for the specific task as well as have the side-effect of being able to run again with the click of a button.
