We Never See Nothing

Years ago I set up a bitcoin wallet, this was before bitcoin was really known to the mass of people. I have the address and it starts with a 7 and has hyphens. It baffles me as to why it starts with a 7 and not a 1 or a 3. I wrote it down and secured it but I didn’t write any other info about it except the address. I do not recall what site I created it on or if it was created on Ubuntu. I guess I was a little too cryptic when I made it, even for myself 🙂 .

I am a bit confused on how I would even go about restoring it as it has been way too long ago since I created it.

Thanks for the responses.
