Back in 2009 I remember putting Bitcoin-Qt on my computer. I went straight over to the site and downloaded, but never put any wallet name or passphrase. Now in 2021 I remembered what I had done. When I checked it with a new computer, it had uploaded many wallet .dat files. It had been syncing for nearly two months nearly.
Is this my wallet.dat from 2009 onwards? When fully synced, will any mined blocks coinbase, or Bitcoin I was rewarded for good questions back then about Bitcoin-Qt, show in my balance? If not, what do I do to receive my rewards? Is this possible?
