I found a vanity address with this verified tool: https://github.com/JeanLucPons/VanitySearch
And now I hold my private key, with BTC I am used to only the recovery seed and I don't know what position I am currently in.
Can I get the seed somehow or does the private key replace it?
The primary thing I'm concerned about is I want to receive all funds in the store at my own address and I want it to be as secure as the address I get in any other wallet.
Thank you very much for your time.
I'm doing research, but this topic seems very complex to me and I'm afraid of getting something wrong and putting myself at unnecessary risk, but what I've understood so far: a private key is +/- the same as a seed except that the seed "controls" the entire wallet, while the private key only controls a specific address, so I should have the funds safe even now and no further steps are needed.
I imported the private key into Electrum and encrypted the file.
