What to do with different currencies?

[kaj_kyle]

Hey, i currently have a problem that prolly many other poker players deal with. I have all my net worth in different currencies. Despite being canadian most of my networth is in euro, follow by USD. I currently have bank accounts in both currencies to avoid getting owned by bad exchange rates. Since i am unsure about the USD, my most recent cash out is just sitting in a USD account doing nothing. Would it be better to, invest this money using the whole vanguard ETF strategy, or to convert this money to Can $ and invest in canada.
My exchange rate with TD is 0.967 to buy USD, 0.941 to buy CAN. Is this a bad exchange rate? If so where can i find a better one?
I have no need of Can $ for the time being, so only really care about long term.
Any advice would be greatly appreciated. thanks.
