What are the necessary apps for currency investment in digital currency?

OKEX: supports the purchase of legal tender, and has digital currency contract products, with a transaction fee of 0.2%. I have invested in digital currency for a long time, and its reputation is still online, with many kinds of transactions.

The interest rate of my previous spot trading in OKEX was 0.15%-0.1%; The rate of futures is 0.02%-0.05%. They are all registered in real names, and there will be no loss of assets. Security and clarity are still very good. Personally, I think OKEX is the most suitable APP for Xiaobai investment that I have ever used.

Digital currency, abbreviated as DC, is the abbreviation of "digital currency" in English, and it is an alternative currency in the form of electronic money. Digital gold coins and cryptocurrency belong to digital currency.

Digital currency is an unregulated digital currency, which is usually published and managed by developers and accepted and used by members of a specific virtual community. The European Banking Authority defines virtual currency as a digital representation of value. It is not issued by the central bank or authorities, nor is it linked to legal tender, but it can be transferred, stored or traded electronically as a means of payment because it is accepted by the public.

Digital currency can be regarded as a virtual currency based on node network and digital encryption algorithm. The core characteristics of digital currency are mainly reflected in three aspects: ① Because of some open algorithms, there is no issuer in digital currency, so no one or organization can control its distribution; (2) Because the number of algorithm solutions is fixed and the total amount of digital currency is fixed, the possibility of inflation caused by too much virtual currency is fundamentally eliminated; ③ Because the transaction process needs the approval of all nodes in the network, the transaction process in digital currency is safe enough.
