What is the legal currency transaction and currency trading?

For the trading mode of digital assets, we often hear legal currency transactions, currency transactions and other methods. So what is a legal currency transaction and a currency transaction? What are the advantages of both? The traditional trading platform only has a legal currency transaction, that is, a legal currency against a digital currency transaction. The legal currency varies according to different countries, such as the US dollar and the Japanese yen. Its advantage is that it can quickly realize the digital currency into a legal currency, that is, a quick withdrawal. However, the drawbacks of legal currency transactions are gradually exposed. With the increasing number of digital currencies, if you want to invest in other currencies, you can either increase your investment or convert existing digital assets into French currency and purchase other currencies. This has greatly increased. Transaction costs and time are becoming more and more inconvenient.
This way the currency trading model is created. As the name suggests, currency trading is a transaction between digital assets that allows investors to invest in digital assets more easily without increasing investment.

Coin trading has more advantages than legal currency trading. First of all, the utility of funds can be more fully realized and rapid arbitrage. For example, if you predict that the price of A currency will drop sharply for a period of time, and the B currency will rise, you can complete the fast switching between A and B. If the forecast is accurate, you can make a quick profit. If the mainstream currency falls across the board, you can quickly switch to a stable currency for safe haven. Second, with the expansion of the application of digital assets, different digital currencies will be used in various commercial fields. For example, blockchain summits, forums and other activities need to pay digital currency. Currency transactions can directly realize the exchange between digital assets, which is convenient and fast, and the economic cost and time cost are relatively economical, and there is no need to increase investment. Finally, the evasion of policy risks. Affected by regulatory policies, some countries and regions have banned financial institutions such as banks from providing services to the cryptocurrency industry, so that exchange between legal currency and digital currency cannot be carried out, and currency transactions can become an alternative for investors. At present, currency trading has become the mainstream trading mode. At the beginning of 2018, the trading volume of currency transactions has exceeded the trading volume of legal currency transactions, and major mainstream exchanges have provided currency trading business. With the wide application of digital currency applications, currency transactions will show greater advantages.
