Hello there,
i've bought bitcoins from bitcoin ATM in Zagreb, Croatia.
How exactly did that happen? At which point did you have your coins?
Then i've downloaded electrum and imported those bitcoins into the account.
How did you import the bitcoins?
Now i have those bitcoins in "watch only" wallets and i cannot send those bitcoins online, there is no send button at all.
How can i get those bitcoins into normal wallet now?
Help us understand what you did and we might have a solution.
