What currency is my account and balance in?

Your account is denominated in euro (€). Balance, Credit, deposits, withdrawals, investment amounts, fees and trade P&L are all displayed and settled in EUR. When you trade non-euro instruments (for example a USD- or JPY-quoted pair), the platform automatically converts that market's profit, loss and margin back into euro for you, so everything on your account stays in a single currency. You cannot switch the account to a different base currency; if you deposit crypto, its value is credited as the equivalent euro amount once your deposit is approved.
