In order to provide a methodology to detect bubbles in time series, Phillips, Wu, and Yu [23] proposed the supremum augmented Dickey-Fuller (SADF) test. This applies a series of right-tailed unit root tests to expanding windows of a time series (with a fixed start date), defined by where r2 is the final data point to be considered in each window, starting at r0 which is a fraction representing the smallest allowed window size and expanding to 1(the complete data set).

Virtual currencies. Like fiat currency, virtual currencies such as Bitcoin, Litecoin, and Ether are intended as a medium of exchange that enables two parties to transact business. But there are important differences: No physical coins or bills. Virtual currencies exist only in computer code. Except for visual representation of Bitcoin and altcoins in advertising and displays, and coin-like tokens that may be produced for marketing purposes, there are no actual coins or bills. Not legal tender. Virtual currencies are not legal tender and are not issued or backed by a government. However, many virtual currencies, which are called convertible virtual currencies, can be redeemed for fiat currency on a number of exchanges. No regulation. Virtual currencies are not regulated by any government agency or authority. However, regulation is being considered, especially where virtual currencies function as securities when they’re used to raise capital and when traded on exchanges.

In the case of cryptocurrencies, academia has barely scratched the surface with respect to identifying the determinants of their prices. For example, studies by Cheah and Fry (2015) and Corbet et al. (2018) claim that Bitcoin has no intrinsic value and that its price has persistently exhibited ‘bubble-like’ behaviour. Makarov and Schoar (2018) find that the prices of Bitcoin, Ethereum, and Ripple differ across exchanges for weeks. Outside of academia, the President of the United States recently tweeted that cryptocurrencies are based on “thin air”.1
Cryptocurrencies work using a technology called blockchain. They are tokens that can be used as a form of payment in exchange for online goods and services. They carry a pre-determined store value of their own, just like any other fiat currency like the US dollar or the Indian rupee. Cryptocurrencies are digitally mined, where very sophisticated computers solve extremely complex computational mathematics problems. Their mining is painstaking, costly and only sporadically rewarding.
The country will be the first to recognise the crypto-currency as legal tender from September 7.
