In 2018 I made an electrum wallet and sent my bitcoins on it, and everything was working. After some time I bought a new laptop, and I recovered my wallet with the seed on the new wallet. In my opinion, everything was correct, so I uninstalled the wallet on the old laptop. Some months later I wanted to check my wallet, and then there was zero credit (with an exit equal to the original amount). I don't know what was going wrong, and I did an update, but without success. Unfortunately, I did not export my private key. I'm pretty sure there is a problem with the recovery. What could have happened?
