Assume I open my BTC Electrum Wallet.
Currently I see only BTC amounts.
Is there a way to automatically show the equivalent EURO amount (calculated by the current exchange rate)?
E.g. in Status Bar at the bottom just behind the current Balance BTC amount ?
Login to your electrum wallet and you will see a green button which shows that you wallet have been connected click on it and go to preference, you will see fiat, click on it and change the fiat currency to EURO. This is for mobile electrum wallet.
Follow EL MOHA direction if it is desktop electrum wallet.
