Is There a Bitcoin–Macro Disconnect?
Cryptocurrencies’ market capitalization has grown rapidly in recent years. This blog post analyzes the role of macro factors as possible drivers of cryptocurrency prices. We take a high-frequency perspective, and we focus on Bitcoin since its market capitalization dwarfs that of all other cryptocurrencies combined. The key finding is that, unlike other asset classes, Bitcoin has not responded significantly to U.S. macro and monetary policy news. This disconnect is puzzling, as unexpected changes in discount rates should, in principle, affect the price of Bitcoin.

Bitcoin vs. the Buck: Is Currency Competition a Good Thing?
Ever since the U.S. established a single currency in the 19th century, the idea of private money has evoked panics and bank failures. In the cryptocurrency era, can the dollar stay sound?

A Short Introduction to the World of Cryptocurrencies
In this article, we give a short introduction to cryptocurrencies and blockchain technology. The focus of the introduction is on Bitcoin, but many elements are shared by other blockchain implementations and alternative cryptoassets. The article covers the original idea and motivation, the mode of operation and possible applications of cryptocurrencies, and blockchain technology. We conclude that Bitcoin has a wide range of interesting applications and that cryptoassets are well suited to become an important asset class.

Deciphering Americans’ Views on Cryptocurrencies
Having witnessed the dramatic rise and fall in the value of cryptocurrencies over the past year, we wanted to learn more about what motivates people to participate in this market. To find out, we included a special set of questions in the May 2018 Survey of Consumer Expectations, a project of the New York Fed’s Center for Microeconomic Data. This blog post summarizes the results of that survey, shedding light on U.S. consumers’ depth of participation in cryptocurrencies and their motives for entering this new market.

The Bitcoin–Macro Disconnect
This paper investigates the link between Bitcoin and macroeconomic fundamentals by estimating the impact of macroeconomic news on Bitcoin using an event study with intraday data. The key result is that, unlike other U.S. asset classes, Bitcoin is orthogonal to monetary and macroeconomic news. This disconnect is puzzling as unexpected changes in discount rates should, in principle, affect the price of Bitcoin even when interpreting Bitcoin as a purely speculative asset.

What Makes Cryptocurrencies Different?
Permissionless blockchains, which support the most popular cryptocurrency networks like Bitcoin and Ethereum, have shown that it is possible to transfer value without relying on centralized trusted third parties, something that is new and remarkable (although perhaps most clearly useful for less developed financial markets). What makes permissionless blockchains able to transfer value without relying on a small number of trusted third parties is the combination of several components that all need to work together. The components themselves are not particularly new, but the combination of ...

Bitcoin Is Not a New Type of Money
Bitcoin, and more generally, cryptocurrencies, are often described as a new type of money. In this post, we argue that this is a misconception. Bitcoin may be money, but it is not a new type of money. To see what is truly new about Bitcoin, it is useful to make a distinction between “money,” the asset that is being exchanged, and the “exchange mechanism,” that is, the method or process through which the asset is transferred. Doing so reveals that monies with properties similar to Bitcoin have existed for centuries. However, the ability to make electronic exchanges without a trusted ...

Beyond the Doomsday Economics of “Proof-of-Work” in Cryptocurrencies
This paper discusses the economics of how Bitcoin achieves data immutability, and thus payment finality, via costly computations, i.e., ?proof-of-work.? Further, it explores what the future might hold for cryptocurrencies modelled on this type of consensus algorithm. The conclusions are, first, that Bitcoin counterfeiting via ?double-spending? attacks is inherently profitable, making payment finality based on proof-of-work extremely expensive. Second, the transaction market cannot generate an adequate level of ?mining? income via fees as users free-ride on the fees of other transactions in a ...

The Lightning Network: Turning Bitcoin into Money
The Lightning Network (LN) is a means of netting Bitcoin payments outside the blockchain. We find a significant association between LN adoption and reduced blockchain congestion, suggesting that the LN has helped improve the efficiency of Bitcoin as a means of payment. This improvement cannot be explained by other factors, such as changes in demand or the adoption of SegWit. We find mixed evidence on whether increased centralization in the Lightning Network has improved its efficiency. Our findings have implications for the future of cryptocurrencies as a means of payment and their ...
