Personally, I think XAUEUR has more investment potential than XAUSD. From the historical monthly line, the price of XAUEUR will definitely exceed XAUUSD.
The current price of XAUEUR is 1125, XAUUSD is 1302, and the historical data of XUAEUR is 1383, XAUUSD1915.
Looking at the overall financial environment and historical record, the future of XUAEUR can be imagined. The euro zone has been volatile in recent years because of Europe's instability, coupled with gold's own risk aversion and risk aversion.
If compared with the us and Europe, who is more likely to become the outbreak point of financial crisis and which is the most unstable, I will choose the latter. In the global financial risks and crisis, currency devaluation, I believe in EUR, USD, was more at select gold, may in the future a point can form a situation - sell EUR, bought was more.
For example, a strategy I think is good, stable, risk-free, and good capital management. The account fund of 5000USD is operated with 0.01lot. As long as you see the low price of XAUSD and XAUEUR in the weekly line cycle, you can buy it, all with 0.01lot. In this way, the profits will be good, stable and free of any risks, about 1000USD--2000USD. If you study well, it will be easier to achieve this goal. If you don't understand anything, you will have a profit of at least 1000USD.
These three varieties can be well studied, can design a good strategy!
