This guy is well known professional coder. The available informations show that he is not here since March 11, 2017, 10:51:09 PM , but i would not think that he left this place. All of us have private matters that are more important than Bitcointalk. In this case i don't have doubt, that happen something that for him was more important. Let's have hope that it wasn't something bad..
Professional coder? Do you have the slightest idea how many were pissed by his coding? Like the gambling websites accused him inserting a backdoor cos their bankroll were wiped out/ vanished.
Because he is also (?) a possible/potential scammer, that doesn't mean that he is not a good coder.
Idk if he is neither a scammer or a good coder, i know though that a lot of people/members have big complains about him and his projects.
I think that Op can't do much, except to wait if this guy come back here...Eventually...
