Hello,

Such a dumbass! I'm currently learning on the steep curve...

Please confirm I really lost my BTC, here's the short story :

- In MultiBit, I created a new receive address and someone sent me 0.4 BTC to it.
- After that I deleted this receiving address from the client (yes, I did this! Was thinking I will not re-use it anymore) before the client got closed, thus not allowing it to produce an updated wallet backup containing this address.

Now, the only I have is my original wallet (without the given receiving address). I have access to this wallet no problem, but this 0.4 BTC transaction is lost forever, right ?

There isn't any chance to re-add the deleted address to this wallet, isn't it ?

THANKS A LOT for your insights as I'm currently quite lost. But at least learning...  :-(

This may be the most effective and easy way I've ever heard of to completely destroy bitcoins.

Thanks for your answers !

So there really is no chance I ever recover this address, although it got generated by the wallet I still posess ?

I'm missing the private key to this address, right ?  No chance to ever get it back ?

Maybe a backup was automatically created. Check the multibit-data folder where your wallet is stored.

I didn't know Multibit allowed you to remove a receiving address. What version are you using?

You're right, MultiBit (using version 0.5.16) doesn't allow deleting a receiving address. I perhaps don't recall right. But then, how come my wallet doesn't display this address anymore ?

I have 6 wallet backups around the time the problem occured, but loading any of these 6 backups doesn't show this address anymore.

If there's still a way to recover these coins (as I still have access to the original file) I would really appreciate the help and reward that. But I think I just have to stop dreaming, right ?

You mean "Reset Blockchain and Transactions" ?

Already tried that, but would love to hear there's still another way...  What do you mean by Repair Wallet command ?

Please, could someone categorically certify these coins are lost ?  I'd rather no more think about and definitely consider them as lost if I knew there's no way...

0.2 BTC to anyone able to help me recover the lost BTC in this ~0.39 BTC transaction (so 50%), knowing I still have the original wallet, it's passphrase and the transaction address showing the ~0.39 BTC.

If it's possible, please help me and cash the reward. Otherwise just tell me I'm a stupid idiot and I wont even bother as it's deserved...

does that program use a standard wallet.dat ? if so you could try loading it with the standard BTC client then do the repair wallet or salvage wallet command

I don't think that option is available in Multibit. I've never seen it.

No, this option doesn't seem to exist for MultiBit. Nevermind, I'll try to forget those 0.4 DGC...

THANKS anyone for the help provided !

My understanding was that, as this original wallet was able to at first create this address based on my private key, it should be possible to tell MultiBit to create a new one with this SAME address and not a random one, thus providing access to the lost coins. But I think I'm not enough into cryptography to understand the whole thing right. Or perhaps someone with better knowledge would be able to recover these coins, but anyway, I'm glad I wasn't talking about 200 BTC...  ;-)

I'll better check my backups from now. Was a long time I didn't loose anything, but it's a good thing life manages to remember us the importance of good backups...

Kind regards

Since currently keys are generated randomly, the only way to generate the same address would be to have it stored somewhere. It gets saved on multibit.wallet, but if it was saved somewhere else, it would be dangerous because the key could be stolen without the user even knowing it was stored there in the first place. HD wallets fix this as they are not random (they have a random seed, but it's the same seed for all new addresses).

Nevermind, I'll try to forget those 0.4 DGC...
I thought this was Bitcoin, not Dogecoin :O
