OK this is 100% a scam
LOL, the guy wasn't even smart enough to make a new bitcoin address, he used the same one as his last scam attempt under a DIFFERENT ACCOUNT.
please everyone, before doing any trades:
1. insist on escrow
2. google "scam [seller name]"
3. google sellers bitcoin address
4. look at seller's profile to see his Date registered. if it's weeks old, move on
5. if they are selling ascii miner shares, ripples, etc , you should be able to find them acquiring it in their post history
etc
