In 2017, when I first started to mine, I made a wallet in wallet.ethereum.org (I stopped briefly after, so I have around 2.2 ETH in that wallet).
Now in 2021 I tried to go to wallet.ethereum.org but the website seems to be down... and according to some instructions I have to transfer it to MEW using JSON or Keystore, which I don't have them anymore..
The only thing I have is the public address, a username and a password,(key icon) address 0x.........
Is there anything I can do with this to access to my ETH address and transfer my 2.2 eth?
Is there someone that can guide me through this?
Thank you in advance.
