Your analysis are most of the time very well thought and good, but you forgot miners who can buy in bulk.
Up 50 Th in 1 go get a reasonable discount, but these whales that come into play now, build their own miners.
Which is incredible cheap to do in China.
They shipped them with pallets to their farm with low electricity costs.
The small guys who bought their gear expensive and have high electricity rates are pushed out of the mining game, which will decrease the difficulty a bit in favour of the big whales and the other small miners who have cheap electricity.
At the end these bastards take a big cut from the pie.
Even for miners with a few hundreds Terahash who don't have electricity costs below 10 cents are having tough times.
well can't disagree with you . You can't mine in Europe unless you can steal power.
what makes things tough to calculate is not cheap miner availability. lots available.
cheap power how much is there of it.
sake of argument sp30 .6 watts is God, Allah, Jesus , King ,Queen , 'Q' (for us trekies) or any other deity Zeus Odin Thor.
but lots of .8 watt gear lots of it.
At .8 watts and 2 or 3 cents a k-watt making money is easy
Heck I have 2 S-3's at 3.5 cents a kwatt but that is my low cost limit.
What is the power limit for an iceland plant?
or for a washington/oregon power plant?
we know they have cheap power but how much?
that availability number is not know to me…
for all I know cex.io can run 300ph at 2 cents a watt and the hashing gear is built . along with the power plants. they just add 20 or 30 ph when they think it is proper.that bolded thought it what keeps me going. the best case for the little guy is that above sentence is true and the
3 or 4 biggest companies are doing just that. If so they
want this to last and will not fuck it up. only time will tell.
Besides mining is more fun then looking up a btc address and a coinbase price.
