so... a3 is a no go, I guess

Long term, A3 can be expected to do "as well" as L3 & S9 are doing at the moment. L3 & S9 are in range of $250-350/mo at the moment. Currently, the A3 looks like it will be doing $30/day for the next 50 days or so then maybe $10/day after March. Still not bad.
Long term, if the project is successful, I see SC at $0.20-$0.60 range within 2-3 years. That part is speculation of course.
I can promise you that after the next batches hit the network, daily profit will be around $2.50. Like the D3 is today. People keep forgetting.....this is ONE COIN. The X11 network was already dangerously thin and it contains several coins. This one.....not so much.
