One more question.
Password of my account doesn't work anymore After I change Active and Owner permision key

Do I understand right that this is standard result of changing the key and now I should create new account and import private key and foret about previuos account?

I'm looking for service where I can check balance by public key. Not by account name

Thanks Permie. It works fine. And now everything is clear to me.

Last question. How to check balance of cold wallet? I'm looking for analogue of www.blockchain.info

Hello Permie

Thank you for your instruction. I'm trying to test it on small amount as you recomend. It seems that it is certainly what I need

I've import new public key to owner permisions. After that I'm not able to make any transaction in openledger anymore. There is notice:

QuoteFailed to broadcast the transaction:
Transaction was not signed. Do you have a private key? [no_signers]

But I can make transactions from my Android application where I import private key.

Just one question. How to import private key to my ledger account? I only find where to import public key
Thank you!

Please help me to transfer BTS from OpenLedger or Poloniex account to new cold wallet

I like to do this to make safe invistition. Just print out cold wallet and put it to the strongbox. I don't like to keep BTS on login-password account
