Mtgox which currency it is safer to keep funds?

[solf]

In which currency it is safer to keep funds in Gox: USD or EUR?
As Mtgox has EUR account in Polish bank, and the seizure of BTC24 account also happened in Poland, there must be a chance that Polish agencies can easily also seize the account of Gox?

As there are rumours that Gox has USD accounts in many banks, maybe it is safer to keep funds in USD?

Thanks for replies.
