4. From the current technology, the next bitcoin in the bitcoin data structure can be divided into 8 decimal places, so the minimum unit of bitcoin is 0.00000001btc, but the transaction can not be so small

On September 20, 1988, the people's Bank of China issued a set of commemorative coins to commemorate the 30th anniversary of the founding of Ningxia Hui Autonomous Region. The front of the coin is designed with the South Pass mosque in Yinchuan, and the name and year of the country are published. The pattern on the back is a picture of Hui girls picking medlar, and the picture of Helan Mountain is above the inner edge. On the top of the outer circle, the words "the 30th anniversary of the founding of Ningxia Hui Autonomous Region" are printed, and on the bottom, the words "1958-1988" are printed with denominations. With a circulation of 1.56 million pieces, this coin is the currency with the least circulation so far in China's commemorative coins, making it the most popular circulating commemorative coin after "CCB coin" and "Tibet coin"
6. currency is a symbol of national sovereignty, and most countries have their own currencies. But there are also countries that use a unified currency e to economic integration, such as the European Union, where more than 20 countries share the euro even within a country, e to different economic systems, different currencies will be used. For example, there are four kinds of currencies in China: RMB, Hong Kong dollar, Macao dollar and new Taiwan dollar. The most common currencies in the world today are US dollar, euro, pound sterling and Japanese yen. Our RMB is also internationalized. It is said that many countries have RMB in their foreign exchange reserves
in our impression, the lower currencies are yen, won and Dong. For example, one yuan RMB can be converted into more than 3300 Vietnamese dollars, and one dollar can be converted into more than 23000 Vietnamese dollars. But they are not the least valuable currencies in the world. The least valuable currencies should be the Venezuelan Bolivar and Zimbabwean dollar after years of vicious currency. In front of the US dollar, their currency value is not worth mentioning, just like waste paper. What many people don't know is that at the beginning of greater Zimbabwe's independence, the Zimbabwean dollar was quite strong, and its initial value was even higher than that of the US dollar. Later, after the land reform in Zimbabwe, the domestic economy collapsed and the currency value went down all the way< br />

8. Other platforms spend part of their total revenue on destroying platform currency, while okb's repurchase fund is 30% of the transaction fee of okex currency.
