I used bitcoin core late in 2016. Since then i haven't used bitcoin and have huge sum in my wallet. Lately when i wanted to get them back then i was told that i need private key.

If i installed the latest version of Bitcoin core with the same wallet phrase will i see that old address back with the balance

Also would like mention i don't have the old computer as i scrapped it and unfortunately no back up to. Is there anyway or am i out of luck.

Any suggestions would be appreciated. i promise a reward to anyone who helps me out?

    Bitcoin core does not use a recovery phrase. If you have a recovery phrase, you were using another wallet – Raghav Sood Jun 2 '18 at 1:11
  • NO Mr Sood not a recovery phrase rather a pass phrase to enter the Bitcoin core wallet. Do u think if i enter that in to a new core client it will get mky old address to which has those bitcoins as i dont have an old wallet back up – user755926 Jun 3 '18 at 2:48
  • If you don't have the original wallet.dat, you don't have any BTC. The passphrase only encrypts the data, it can not be used to recover it without the wallet.dat – Raghav Sood Jun 3 '18 at 4:28

TL;DR: No. Your bitcoin-core pass-phrase cannot be used to recover your bitcoin.

i was told the need of a private key

If you have the private key, you can recover access to your bitcoin.

If you have a recovery phrase and know which bitcoin wallet you used, you can recover the private key and recover access to your bitcoin.

Otherwise those bitcoin are gone forever.

Expect to receive lots of email from scammers and very convincing professional conmen.

Don't give anyone your private-key or your recovery-phrase. The only circumstances you should ever do that is in front of a lawyer paid by you with proof of the helper's identity and a signed contract in her hand. Otherwise you will lose even more money.

People can help you without knowing your private-key or recovery-phrase. If they say they can't help you without those things, they are conmen.

If i installed the latest version of Bitcoin core with the same wallet phrase will i see that old address back with the balance.

No.

Any suggestions would be appreciated

Are all of the words in your passphrase in the BIP39 list? If so it is a recovery-phrase not a pass-phrase. If so it would be associated with a different type of wallet than the "bitcoin core" wallet.

If so, download a wallet application that uses BIP39 and try using your recovery phrase in it. Be very careful not to download malware. Start with wallets that don't require an online service to work.

Bitcoin core "passphrase"

Bitcoin Core Settings menu

Note that in the "bitcoin core" wallet, the Passphrase is used to encrypt your wallet. It is not a recovery phrase. You cannot recover access to your bitcoins using only the pass-phrase of a lost wallet.

  • Run Bitcoin-Core
  • Select Help (to the right of Settings)
  • Select Debug Window
  • Select Console
  • If you encrypted your wallet, unlock it by entering walletpassphrase "YourLongPassphrase" 600 next to the > input box
  • Next to the > input box type importprivkey <bitcoinprivkey> (Note that the private key must not have spaces, remove them if they are included in your backup)

Example: importprivkey 5KJvsngHeMpm884wtkJNzQGaCErckhHJBGFsvd3VyK5qMZXj3hS

Note that the 'bitcoin core' wallet does not use a recovery phrase. You cannot recreate your private key from a recovery phrase using bitcoin core. The only "pass-phrase" used with bitcoin core grants access to the wallet, it is not the private key and cannot be used to recreate the private key.

Without the private key, the bitcoins are gone forever.

  • Thank you so much for all ur comments but my i am pointing to a particular query which stands as.... If i download the latest bitcoin core and enter the pass phrase which i used for my old core client will it still show up my old btc address which has my old mined coins. I dont have a back up of old wallet.dat file. Thanks once agian for ur suggestions – user755926 Jun 3 '18 at 2:51
  • @user755926: See amended answer. Your old pass-phrase for bitcoin core only protected access to your wallet, it is not a recovery key. You need to know the private key. If you don't have the private key, your bitcoins are gone forever. – RedGrittyBrick Jun 3 '18 at 11:38
