What kind of hardware did he have to solve 10 characters in 11 minutes! Thats awesome and is exactly what I need. going to look into this as well now!
You can't do it in that short time, as you don't have the public key.
1 year ago, user PawGo calculated exactly your case (10 missing WIF characters) but
with the public key in less than 11 minutes.
Not bad, no?

10 missing WIF characters - Less than 11 minutes
on old CPU. GPU performance - to be seen.
That's fantastic. I'll have to go back to check Pollard's kangaroo algorithm again.
Ok that makes sense. Seems like bitcrack is my only hope at this point. Thank you for your continued help. Should I solve this I would love to pay everyone a bounty who has helped
