user127368: Recently I converted some of my BTC to Euros on Coinbase. I needed €5000 euros exactly. The fee was €74.50, ok fine. That left me with €4925.50.
I haven't made one transaction since, but logged in now and see that I have only €4248.63 and price is Euro price is €0.86.
I have to say, i'm confused here. Can anyone explain? Thanks.

Are you sure the btc2eur conversion was successful?

This could look like the btc2eur conversion was unsuccessful and so your "account value" has ever since shrunk.
Or could look like the first action was really btc2usd, not btc2eur. This one is somewhat common.
Double check everything and ask their customer support.
