Cryptocurrency is a digital currency managed by a network of volunteers called “nodes”. Instead of a single intermediary, cryptocurrencies are maintained by a collective of computers that contribute their computing power to solve a series of mathematical puzzles. Miners are rewarded with a small amount of cryptocurrency for validating transactions. However, this work requires intense computer power and electricity. The cryptocurrency holders who have the most wealth and stakes are the ones who are chosen to make the blocks.
The primary reason cryptocurrency is so popular is because it is decentralized. There is no central bank to regulate it, so there is no need for centralized banks. Because cryptocurrencies are decentralized, the blockchain system helps ensure that they are not counterfeited. A large portion of the population does not have access to a bank or payment system. As a result, the problem of double-spending is resolved. Despite the fact that blockchain technology does not address the toilet issue, it has the potential to spread digital commerce worldwide.
The cryptocurrency market has gone wild in recent months. New cryptocurrencies are emerging every day, each with a big story to tell. Although few survive their first months, speculators are constantly pumping and dumping them, creating a zombie-like effect. Some cryptocurrencies, however, can survive. This is because there are third-party providers that allow cryptocurrency holders to convert their cryptocurrency into gift cards. Unlike traditional bank accounts, cryptocurrencies can be used to buy items at retail stores or make payments to friends.
