About 2 years back I bought 1 ethereum, or 1.04862 to be exact.

I put it in some wallet and printed a backup of my address and key.

So I have the following unencrypted information on a piece of paper:
address, path, balance, privkey

I thought at least that should show me if the ethereum still exist and the transaction history?
What would be the easiest way to quickly confirm my wallet?
