Some relevant Information about the definition of cryptocurrencies on Wikipedia:

Formal definition

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.

Altcoins

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”.

Crypto token

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.

And for more information about Aruba you can follows an excerpt of Wikipedia:

Aruba ( ə-ROO-bə, Dutch: [aːˈrubaː, -ryb-] (About this soundlisten), Papiamento: [aˈruba]) is an island and a constituent country of the Kingdom of the Netherlands in the mid-south of the Caribbean Sea, about 29 kilometres (18 mi) north of the Venezuelan peninsula of Paraguaná and 80 kilometres (50 mi) northwest of Curaçao. It measures 32 kilometres (20 mi) long from its northwestern to its southeastern end and 10 kilometres (6 mi) across at its widest point. Together with Bonaire and Curaçao, Aruba forms a group referred to as the ABC islands. Collectively, these and the other three Dutch substantial islands in the Caribbean are often called the Dutch Caribbean, of which Aruba has about ​13 of the population.

Aruba is one of the four countries that form the Kingdom of the Netherlands, along with the Netherlands, Curaçao, and Sint Maarten; the citizens of these countries are all Dutch nationals. Aruba has no administrative subdivisions, but, for census purposes, is divided into eight regions. Its capital is Oranjestad.

Unlike much of the Caribbean region, Aruba has a dry climate and an arid or desert, cactus-strewn landscape. This climate has helped tourism as visitors to the island can reliably expect warm, sunny clear skies year-round. Its land covers 179 km2 (69.1 sq mi) and is quite densely populated, by 101,484 inhabitants, as at the 2010 Census. Current estimates of the population place it at 116,600 (July 2018 est.) It is south of the typical latitudes of hurricanes but was affected by two in their early stages in late 2020.
