5500$ for 3830 ghs (4.7 times A3) with the similar power around 1400 watt, shipped with the same A3 batch 2 (20+ march)
Right now I can make $20 a day with A3 before elect. In my country, they have the same elec price around $3.5 a day. So I guess in April, A3 will mining for $10 - $3.5 = $6.5 nett a day. While B52 mining every day $47 - $3.5 = $43.5 nett a day.
If bad come worst A3 mining $5 - $3.5 = $1.5 nett a day, then B52 still mining every day $23.5 - $3.5 = $20 nett a day.
D3 part two, but not Bitmain fault this time 😁
Actually the price of the B52 is the same as buying 4 A3s per hash unit. So it should be about even in terms of ROI
