Bitcoin Forum

Hi !

I'm looking for a website helping to find lost wallet bitcoins by using its spent transactions history.
Like a specific bitcoin blockchain explorer focusing on debit / spend transactions only, avoiding small amounts.

After finding the last spent transactions, the service will monitor the last address where the spent coins are
up to go to a known address where you can you can claims your coins.

Do you know if a service like that exist ?

Well, the truth is that I'm building something similar to learn blockchain coding, I dont want to make more work on it
if it's already exist or if doesn't make interest to others.

Waiting for your replies. If the service is interesting some one telle me, I will provide the url for testing when available

PS: bonus question : I found some website refenrencing famous bitcoin address (scam or donations) do you kown if the is a service just asying hey this bitcoin address is a bittrex address or another exchange or any service/shop accepting bitcoins ? 

I'm not sure I follow you. What's a 'lost wallet'? From where would you need to work your way up the blockchain, and why? Also, have you considered that bitcoin addresses should be used only once, which is why addresses aren't usually 'known' in the sense that they would identify a person like e.g. email addresses or PGP public keys do?

The main issue for such thing is the accuracy of the results. Due to popularity of BTCitcoin mixing services, it has little to no chance of success (unfortunately).

There's WalletExplorer (https://www.walletexplorer.com/).

Sorry I wasn't clear, instead of "lost wallet" it's better to write "an address with a lost private key" (like when an exchange is hacked and their users loses their bitcoins). I know that bitcoin addresses should be used only once but i realized that most main stream users still using the same address from their exchange.

Thanks for the url, I'll check that service

For now, if I understood you thoroughly, that doesn't exist as tracking the bitcoins been moved from one account to another requires a technology that is yet to be introduced. May be in the future.

I read some additional posts here and I saw your adjustments to mean lost Private Keys. I saw that a URL was given you by a contributor. It will be nice if we can check that out an give a feedback. But i doubt if that would be easy an straight as an arrow

On bolded part. These service would really f*cked this idea for sure. One usage of these service would really put you off-track on what you are trying to trace up which means accuracy wont really be there.
