Some relevant Information about the definition of cryptocurrencies on Wikipedia:
According to Jan Lansky, a cryptocurrency is a system that meets six conditions:
In March 2018, the word cryptocurrency was added to the Merriam-Webster Dictionary.
Tokens, cryptocurrencies, and other types of digital assets that are not bitcoin are collectively known as alternative cryptocurrencies, typically shortened to “altcoins” or “alt coins”. Paul Vigna of The Wall Street Journal also described altcoins as “alternative versions of bitcoin” given its role as the model protocol for altcoin designers. The term is commonly used to describe coins and tokens created after bitcoin. The list of such cryptocurrencies can be found in the List of cryptocurrencies article.
Altcoins often have underlying differences with bitcoin. For example, Litecoin aims to process a block every 2.5 minutes, rather than bitcoin's 10 minutes which allows Litecoin to confirm transactions faster than bitcoin. Another example is Ethereum, which has smart contract functionality that allows decentralized applications to be run on its blockchain. Ethereum is the most-actively used blockchain in the world according to Bloomberg News and has the largest “following” of any altcoins according to the New York Times.
Significant rallies across altcoin markets are often referred to as an “altseason”.
A blockchain account can provide functions other than making payments, for example in decentralized applications or smart contracts. In this case, the units or coins are sometimes referred to as crypto tokens (or cryptotokens). Cryptocurrencies are generally generated by their own blockchain like Bitcoin and Litecoin whereas tokens are usually issued within a smart contract running on top of a blockchain such as Ethereum.
And more about cryptocurrencies in general:
A cryptocurrency (or crypto currency or crypto for short) is a digital asset designed to work as a medium of exchange wherein individual coin ownership records are stored in a ledger existing in a form of computerized database using strong cryptography to secure transaction records, to control the creation of additional coins, and to verify the transfer of coin ownership. It typically does not exist in physical form (like paper money) and is typically not issued by a central authority. Cryptocurrencies typically use decentralized control as opposed to centralized digital currency and central banking systems. When a cryptocurrency is minted or created prior to issuance or issued by a single issuer, it is generally considered centralized. When implemented with decentralized control, each cryptocurrency works through distributed ledger technology, typically a blockchain, that serves as a public financial transaction database.
Bitcoin, first released as open-source software in 2009, is the first decentralized cryptocurrency. Since the release of bitcoin, other cryptocurrencies have been created.Cryptocurrencies on Wikipedia (Source)
And for more information about Argentina you can follows an excerpt of Wikipedia:
Argentina (Spanish: [aɾxenˈtina]), officially the Argentine Republic (Spanish: República Argentina), is a country located mostly in the southern half of South America. Sharing the bulk of the Southern Cone with Chile to the west, the country is also bordered by Bolivia and Paraguay to the north, Brazil to the northeast, Uruguay and the South Atlantic Ocean to the east, and the Drake Passage to the south. With a mainland area of 2,780,400 km2 (1,073,500 sq mi), Argentina is the eighth-largest country in the world, the fourth largest in the Americas, the second largest in South America after Brazil, and the largest Spanish-speaking nation by area. The sovereign state is subdivided into twenty-three provinces (Spanish: provincias, singular provincia) and one autonomous city (ciudad autónoma), Buenos Aires, which is the federal capital of the nation (Spanish: Capital Federal) as decided by Congress. The provinces and the capital have their own constitutions, but exist under a federal system. Argentina claims sovereignty over part of Antarctica, the Falkland Islands (Spanish: Islas Malvinas), and South Georgia and the South Sandwich Islands.
The earliest recorded human presence in modern-day Argentina dates back to the Paleolithic period. The Inca Empire expanded to the northwest of the country in Pre-Columbian times. The country has its roots in Spanish colonization of the region during the 16th century. Argentina rose as the successor state of the Viceroyalty of the Río de la Plata, a Spanish overseas viceroyalty founded in 1776. The declaration and fight for independence (1810–1818) was followed by an extended civil war that lasted until 1861, culminating in the country's reorganization as a federation of provinces with Buenos Aires as its capital city. The country thereafter enjoyed relative peace and stability, with several waves of European immigration, mainly Italians and Spaniards, radically reshaping its cultural and demographic outlook; 62.5% of the population has full or partial Italian ancestry, and the Argentine culture has significant connections to the Italian culture.
The almost-unparalleled increase in prosperity led to Argentina becoming the seventh wealthiest nation in the world by the early 20th century. According to the Maddison Historical Statistics Project, Argentina had the world's highest real GDP per capita in 1895 and 1896, and was consistently in the top ten before at least 1920. Currently, it is ranked 61st in the world. Following the Great Depression in the 1930s, Argentina descended into political instability and economic decline that pushed it back into underdevelopment, although it remained among the fifteen richest countries for several decades. Following the death of President Juan Perón in 1974, his widow and vice president, Isabel Martínez de Perón, ascended to the presidency. She was overthrown in 1976 by a military dictatorship. The military government persecuted and murdered numerous political critics, activists, and leftists in the Dirty War, a period of state terrorism and civil unrest that lasted over until the election of Raúl Alfonsín as president in 1983.
Argentina is a developing country and ranks 46th on the Human Development Index, the second highest in Latin America after Chile. It is a regional power in Latin America and retains its historic status as a middle power in international affairs. Argentina maintains the second largest economy in South America, the third-largest in Latin America, the fifth largest in the Americas, and is a member of G-15 and G20. It is also a founding member of the United Nations, World Bank, World Trade Organization, Mercosur, Community of Latin American and Caribbean States and the Organization of Ibero-American States.Source
