$200k in BTC is only 400btc
which equates to 13btc a day
which equates to 0.55btc an hour
which equates to 0.09259259 a block

which is 0.4% of network hash or 640 terrahash units or 2500 avalon3 units

just a shame the equipment is obsolete quite quickly and having to endlessly keep buying more
the 0.59btc per avalon unit x2500 units=1500coin cost.

so lets work out if they will break even:
with hashrate at 100peta in june, then last month averaging 125peta this month 150peta
=roughly 25% increase per month(ill use this as bases of simple math calculations per month).

so this months 400 coin will be made, 300 next month. 225 in october.
168btc in november
126btc december
95btc in january
72btc in february (cut off point as 72btc is less then 80btc of electric ($40k at $500/btc=80btc electric))
=about 1393 coin by february
minus off the 80btc electric costs per month (560coin electric cost from now till february)
=833btc by coin hoard by february if selling coin for electric. or 1393 if hoarding all coin.

either way the avalon3 miners are not profitable, which they will realise by the time it gets to february
