Thank You All for your answers.
I logged in to my Blockchain account and I found the old address with the Bitcoin in it.
There is a description that says:
"Imported Bitcoin addresses
Imported funds are not protected by your Recovery Phrase. To ensure these funds are secured, please transfer them directly into your wallet.
'Verify Message' (button)"
"Address 12D....
Balance 0,00127 BTC
'Actions'
Manage (menu)
- Archive
- Private Key
- Sign Message
- Send
"
What does this mean - what would happen if I pressed 'Verify Message' button?
I'm a little anxious, because earlier when I tried to use the Bitcoin in my Blockchain account a popup appeared and asked me to tap it to transfer the Bitcoin to the wallet from my address, unfortunately I did tap it and I regretted this action immediately, because I lost more than 10 $ by tapping it.
What should I do, which 'Action' could I choose that would maximize the amount of Bitcoin I can use?
If I choose the 'Send' option I can send the full amount of Bitcoin (minus the transaction fee) to an another Bitcoin address?
Thank You for your answer in advance!
