This question already has an answer here:
Long story short, I got into ether mining back in '16, even went as far to buy some ethers and sent it to... wherever? I stopped in Dec '16 and forgot all about it, packed up and stored the PC while I traveled. I finally got a new place and booted up the PC, showing my ether info in etherscan.io - I can login and definitely know the password, however I cannot send what I have because etherscan.io is not a wallet... cannot remember where it is, but I DO have my address. cpp-ethereum is still set up on this win 10 machine, and I opened geth up and inquired to my balance - it said 0! even though etherscan.io shows my actual balance! how do I access my funds and transfer it to coinbase?
Thanks! - J
