Due to the drop in the dollar buying Euros was the smart move.
In light of the coming inflation buying Euros isn still smarter.

If you had traded dollars for Euros about 3 years ago like George Soros your return rate would be 30% instead of 3%.

If you had done so 2 years ago like Warren Buffet your return would be clise to 20%.

Today your return would still beat 3%.
