The price they are asking seems way too high for a miner that will only see a month of pre-halving operation (if they ship on time). The only way this price makes sense to me is if you expect BTC price to double or diff to halve before or very close after the halving. If that happens, then ROI with 5c/kWh power is about 250 days. If price and diff remain the same, then ROI with 5c/kWh power is 435 days, 500 days if they are late and you miss all pre-halving mining. Judging by how Bitmain has priced their miners in the past, I'm guessing they'll crush this price when they release their 5nm miners.
funny you should mention this. I was on pangolin website looking at the m21 a 60 watt machine which ships to usa in 5 days.
cost of 600 bucks does 27 th
so buy 3 send one to your brother and one to your house and one to you mother. legally avoids trump tax
cost of 3 x 600 = 1800 for 81 th the three pieces are in stock and should show in 10 days or less.
but 1 m30 = 2700 for 81th the unit will show in 30 days if lucky you may pay 650 trump tax cost of 3300
so same hash for 900 to 1500 more usd. and at least a 20 day delay to get the 38 watt single m30 vs the 60 watt 3 m21
for 20 days 80th = 250
so I am 1150 to 1750 in the hole buying the new gear assuming they show on time. (hmm how often is that)
38 x 80 = 3100 watts
60 x 80 = 4800 watts
a 1700 watt difference lets make it 2000 that is 2 kwatts x 24 = 48 kwatts a day lets make it 50 kwatts a day
at 5 cents that is 2.50 a day in power savings. so 1150/2.50 = 460 days and 1750/2.50 = 700 days
so buying 1 m30s will take 460 to 700 days to make up the price difference
over buying 3 m21 pieces of gear.
So as much as you may want the m30s it simply makes close to zero $$ sense at 5 cent power.
you can argue it makes sense at 10 cent power but it still means 230 to 350 days to make up for the extra cost of the m30
and we all know mining at 10 cent power = loser for the last few years.
I did factor with and without trump tax.
I did not factor what if the psu breaks
on the m30s you have zero hash
on the m21 you have 3 pieces so 1 dead one means you have 53 or 54 th left.
So for those that want the best gear they are paying a high premium for it.
