I recently realized that my understanding of currency symbols is a bit messy, especially the euro symbol and the dollar sign—they look similar but actually represent completely different things. In fact, over 30 countries worldwide use the $ symbol; for example, USD is US$, CAD is C$, HKD is HK$, AUD is A$, and this helps to distinguish them clearly.

The most easily confused symbol is ￥, which Japan uses to represent the Japanese Yen, while China uses it to denote the Renminbi, so the correct notation should be CNY￥100 or JPY￥100. Another more special symbol is ฿, which in foreign exchange represents the Thai Baht, but in the cryptocurrency world, it is the symbol for Bitcoin.

If you want to quickly input the euro symbol € and other common currency symbols, Mac users can press Shift+Option+2 to type the euro sign, the British pound is Option+3, and the US dollar sign is simply Shift+4. On Windows systems, the euro symbol can be entered with Alt+E, and the British pound with Alt+L. Mastering these shortcuts is actually very helpful when doing forex trading, as common pairs like EUR/USD can be instantly recognized as the euro to US dollar exchange rate.
