What is digital currency?

Digital currency is a virtual currency based on a node network and digital encryption algorithm. The core features of digital currency are mainly reflected in three aspects: ① Since it comes from some open algorithms, digital currency has no issuing entity, so no person or organization can control its issuance; ② Since the number of algorithm solutions is determined, the total amount of digital currency is fixed, which fundamentally eliminates the possibility of inflation caused by the excessive issuance of virtual currency; ③ Since the transaction process requires the approval of each node in the network, the transaction process of digital currency is safe enough.

How does digital currency make money?

Leasing mining machines to mine digital currencies is a way to make money.
In blockchain, mining is the process of verifying and processing transactions by solving complex mathematical problems with computers. Miners contribute their computer computing power to the network in exchange for a certain amount of digital currency as a reward. This requires considerable computing power and a stable power supply, so mining may not be easy for individuals, and most miners form mining pools to mine together.
