Retrieving bitcoin from old seed 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.
Discovering which wallet this was generated from may be important. Over the years different words and derived paths have been used by different software.
