Meanwhile, there has been plenty of speculation that bitcoin’s big rise may have been due to a pump-and-dump scheme. One theory that the U.S. Justice Department is reportedly looking into is that the digital coin Tether (which is supposedly pegged to the U.S. dollar to make for a less volatile cryptocurrency) was used to manipulate the bitcoin market and cause a large run-up in price. This theory stems from an academic paper, which cast Tether in a very damning light. And it also led many to believe that the initial bitcoin craze was manufactured and destined to bust.
Cryptocurrency transactions are recorded on a decentralized ledger. This ledger is called a blockchain. Every time crypto is bought or sold, the transaction is added to the blockchain — a public database of the transactions, which is available to other crypto holders. Anyone can join and participate in the blockchain, but data on individual transactions — and the people involved with them — are secured using cryptography (the basis for the term cryptocurrency). For each transaction added to the blockchain, there’s a digital validation process to verify it and prevent fraud.
