Topic: need help bitcoin (Read 197 times)

I don't think this will help him recover his list coins. If his wallet is fully synced and he still can't see any balance or any transaction then importing the wallet (seed/private keys..) into another wallet software will not help.
However, you raized a very good point! OP, you said you created a new wallet then you generated a new address, right? If the address you have generated is a legacy address (starts with bc1) then (most likely) this is not the wallet you are trying to recover.
You said one of your friends previously helped you recover your wallet. Do you teust him? Why don't you call him and ask for his help or at least ask him what you should do!

Since the wallet is fully synchronized and there are no passphrase, you can extract the private key, import it to electrum wallet as I guess you are not familiar with bitcoinCore

Window>>Console and then use dumpprivkey command, copy private keys and import it using p2pkh: (I think your wallet from 2013 will have Legacy addresses only)

You can then check the balance, create a new wallet, create a passphrase and send coins to the new wallet if you want to continue using BitcoinCore.

Don't bother sending a PM to anyone claiming to help you if they don't have any reputation on this forum. If you really want to help then post your advice here like what everyone did above. No point going into PM if you want to help, you can even try posting in French plus English language if that's what you want to address through PM.

I can help you.

Please send me private message.

Thanks

Modifying the database cache size from 550 to 3000 MB shouldn't cause any issue with your wallet file or blockchain, it mainly affects the node's performance.
If balance is the issue, the first thing you should try is: rescanblockchain command to check if the last scan missed some transaction(s).

But based from the size of 550MB, I think you're talking about "prune block storage" size instead of dbcache.
If it's the case, you cannot use the command above with the default parameters, for pruned blockchain, the "start_height" and "stop_height" must be indicated based from your available blocks.

So here are your current options:

• If it's not the dbcache, use the mentioned command by opening the 'Console' in "Window->Console", select the correct wallet,
  and enter rescanblockchain command.
• If it's pruned, you should get your 'pruneheight' from getblockchaininfo command,
  then rescan starting from that height using rescanblockchain "start_height" command (replace "start_height" with your pruneheight value).
  Take note that if the missing transactions aren't included to the scanned blocks, it wont be scanned still.

Hello, I describe my wallet:

HDwallet
old from 2013 and 2019
bitcoin core has synchronized with the blockchain and is synchronized,
I have no passphrases!
I modified the DBcache… around 3000 instead of 550 MB!

I tried to import my wallet, but it doesn't work, it doesn't show the bitcoins!
someone helped me the last time, but now I'm stuck.. no way to find my old wallet with its keys and addresses has worked!
I searched the forums but nothing helped me!
the last time I succeeded but there were no real bitcoin exchangers… strictly speaking, against state currencies.

Hello I describe my problem:

and the problem is simple: I did a simple manipulation: create a new wallet and add an address to my new wallet,
to change the wallet.dat file that was stagnating there!

Since then I have not seen these btc which are on these new wallets and these new bitcoin addresses where they must be

J'ai fait un copier coller pour traduire !

Bonjour je décris mon wallet :

HDwallet
vieux de 2013 et 2019
bitcoin core a synchronisé avec la blockchain et est synchronisé,
je n’ai pas de passphrases !
j’ai modifier le DBcache… environ 3000 au lieu de 550 mo !

j’ai essayé d'importer mon wallet, mais ça ne marche pas, ça ne montre pas les bitcoins !
quelqu’un m’avait aidé la dernière fois, mais là je bloque.. aucun de chemin pour retrouver mon vieux wallet avec ses clefs et ses adresses n’a marché !
je cherche sur les forums mais rien ne m’a aidé !
la dernière fois j’ai réussi mais il n’y avait pas de vrai échangeurs de bitcoins… a proprement parlé, contre des monnaie étatiques.

Bonjour je décris mon problème :

et le problèmes est simple : j’ai fait une manipulation simple : créer un nouveau wallet et  ajouter une adresse a mon nouveau wallet,
pour changer de fichier wallet.dat qui stagnait là !

Depuis je n’ai pas revu ces btc qui sont sur ces nouveaux wallets et ces nouvelles adresses bitcoin ou ils doivent êtres

I don't understand what you are trying to say but you mean you modify the dbcache but it corrupts the Bitcoin core downloaded blockchain files?

And you want to recover your bitcoin from your wallet?

I believe you may resolve this issue by running Bitcoin Core with the "-reindex" option.

Hello,
the modification of dbcache, he corrupts,
the blockchain bitcoin-core
and the luck to restore wallet.dat
in bitcoin-qt
for recover my bitcoins ?
