Very good! Thanks
What does the column Log(2) mean exactly? What are the calculations behind it?
Log(2) = Logarithm to the base 2 of the decimal value.
How did you find the private key for the first address?
Brute force
So could I just use vanitygen & type in
vanitygen.exe -t 50 -v [address]?
Or is there different else to do
