If you are trying your hand at being a good investor, even if you are the best, you will reach a wall unless you diversify wealth into different currencies.

Owning multiple homes is great, but if they are all priced in the same currency then you open yourself up to risks in devaluation and depreciation.

By trading in the forex market you get to take advantage of growth in international markets by buying those currencies as well as starting up a new savings account that is donominated in a foreign currency. Another great aspect of trading forex is that you can trade when the markets are open in other time zones, so you can still have market liquidity even at 2AM!
