I'm using the core wallet, so I setup a second pc with a fresh install of windows 10 out of a old mining rig. I installed ABC wallet, but it just freezes after downloading about 60% of the blocks. Restarting, reinstalling doesn't fix it. Now, I'm trying to do it with bitcoin unlimited wallet, which is taking days. Is this my best option?
FreeBitcoins.com allows you to dig and dump in minutes.
You can dig individual addresses or whole .dats' in a few clicks.
Only dig empty address though obviously and never trust that address again (but save it "just in case".)
