You A3 owners are lucky this time. Buttmain didn't mine the hell out of A3 for months before shipping the A3. They finally tossed you the bone to make up for D3 and to send a death threat to the Sia asic devs. But dont' expect Buttmain to be as generous next time.
Actually, that's the new standard now. They're shipping within 10 days instead of 1~2 months like they used to. Check the last batch of the L3+ they posted. They shipped them within 10 days as well
Not the S9s (that accepted wire transfer last time btw), bitmain always surprises with something.
