so the Total Bitcoins to ever be produced : 21,000,000
and back in the day i had 27BTC back for a few jobs i did when they were worth next to nothing
that computer was long since gone, what happens to the 27 do they get found by some company or the miners or what?
I think your 27 bitcoins also gone with your computer. 27 bitcoins for now is a huge amount of bitcoins, do you ever try to find your old computer ? because i think it's really worth if you can found your pc.
I think you can do nothing now , as you have lost the computer and you have loaded your bitcoins in desktop software so if you have the key of passphrase or wallet.dat file with out this you can do nothing . Just forget it , if you found the passphrase then you can recover it back.
