In January 2016 I bought a bitcoin but I don't remember what program I used. I used the seed code and now I entered a wallet. However, it is empty. And it also says there haven't been any transactions ever. Did I enter a wrong seed or someone else's seed? Or can the history be removed? Or does it matter in which program I use the seed? Or does it have to do with the halving? Please help me to recover my BTC.
so this question is not suitable for this forum because it requires back and forth diagnoses. i suggest you create a thread on bitcointalk.org forum or the bitcoin beginners subreddit. be sure to mention what software you've tried restoring from seed in.– AbdussamadJun 18, 2020 at 20:13
Does this answer your question? Is a 'seed phrase' independent of the type of wallet?– Tony SanakJun 18, 2020 at 22:24
If that was a BIP39 mnemonic phrase, the upcoming new version of Electrum will provide a scanning/probing feature for wallet recovery purposes: github.com/spesmilo/electrum/issues/6155– Chris ChenJun 22, 2020 at 9:08
Discovering which wallet this was generated from may be important. Over the years different words and derived paths have been used by different software.
A good place to start is to look through https://walletsrecovery.org/ which may help jog your memory and a start on the recovery process.
