I've generated a large number of bitcoin addresses and private keys - I can receive money at the bitcoin addresses easily enough, but what's the easiest way to spend that money?
Basically, I've just got the 58 character private keys - what software can I easily import that into to aggregate the funds? What's the easiest way to do that? Thanks!
I've been doing this myself. The only way I know is to import into MtGox with the website (not the app). I sure would like a smartphone app to do this.
