Hi and thank you for taking the time to read my post.
I have some bitcoin from a few years ago and if i type the wallet address into blockchain.com I can see the wallet balance.
I have the private key stored away but my understanding is i also need a public key ?

The only information i have is the wallet address and the private key.
I have no idea were i purchased the bitcoin from or how its stored.
Any help would be really appreciated.
Thank you
