The next phase in the crypto mining process is to compile a list of all transactions, which is subsequently included in a new unconfirmed data block. It avoids “double spending” of any cryptocurrency and keeps a permanent and public record by adding their transaction to the blockchain, once the verification procedure is complete. The record is immutable, which means it can never be changed or corrupted.

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.
