Cryptowww
Cryptocurrencies are digital or virtual tokens that use cryptography to secure their transactions and to control the creation of new units. Cryptocurrencies are decentralized, meaning they are not subject to government or financial institution control. Bitcoin, the first and most well-known cryptocurrency, was created in 2009. Cryptocurrencies are often traded on decentralized exchanges and can also be used to purchase goods and services.
Cryptocurrencies are often viewed as an investment asset and their value can be affected by a variety of factors, including global events, regulation, and media sentiment. Bitcoin, for example, reached a high of nearly $20,000 in December 2017 before declining in value throughout 2018.
There are a variety of cryptocurrencies available, including Bitcoin, Ethereum, Litecoin, and Bitcoin Cash. Cryptocurrencies are often traded against each other on decentralized exchanges and can also be used to purchase goods and services.
