Starting with the euro, you have a better chance to win foreign exchange, because the euro is like a large-cap stock of China stock. It takes time to rise and fall, and it's easy for you to get in and out. When you are mature, you can consider the pound, a small-cap currency with a large spread and fast fluctuation. There is also the Japanese yen, which is an eventful currency, including the manipulation of the Japanese government and the game of big international funds. There is often smoke on the yen. Hehe, you are also on the battlefield.
