I'm completely ignorant on buying currencies as a hedge or a safer place than the US dollar.
With a strong dollar would it be wise to scope a few percentages of like the Swiss Franc?
Is there anything like strong in paper currency? If there is, I don't think there will be parity between Euro to USD. As long they are fighting inflation by printing arbitrary paper with values written on them, they will always struggle to maintain them during crises.
Don't ever make the mistake of buying a currency as a hedge against inflation, you could buy as many bunches you want but trust me, in a few years time, you will only be able to spend them on pairs of shoes, clothes and dinner.
Just a thought I've never had before.
I hope you have heard of Bitcoin, buy it, secure it, and hold it for some time, you will know how transparent and very efficient it is to capitalize your investment on Bitcoin.
