Half minute is more like it.
The ordering site will crash for sure
I think ngzhang should use some lottery method to decide who will get an order
At the time batch 2 opens, there was still guess that Avalon spent all the pre-order money to only made 2 prototypes, but now it is confirmed that they can deliver
But, till May/June the network will rise to at least 200TH:
Asic miner first round 12T
Asic miner second round 50T
Avalon batch 1 20T
Avalon batch 2 40T
Avalon batch 3 60T
BFL
At that time one Avalon will mine about 1-2 coins per day, fall back to the same performance of a 6 GPU machine one year ago. Of course the btc price now has made it 10x profitable than one year ago, so 2-3 month ROI still possible, but BFL is a big variable here
