There are many benefits to trading forex as an asset class:
Unlike other markets, it trades around the clock throughout the working week.
Forex is also the most liquid market in the world, by far. Over $6.5 trillion is exchanged on the global currency markets every day. Forex is also the original decentralised market, long before crypto even existed.
It’s the lifeblood of the global economy and touches all other markets as every single transaction, whether it’s the procurement of commodities, the purchasing of bonds, or the trading of stocks, involves a foreign exchange component, especially if your national currency is not the US dollar.
Finally, forex is a great training ground for traders. As well as touching all other markets, FX tends to be less volatile than other asset classes, so potential drawdowns tend to be smaller than in other asset classes.
