It could pad the margins, though.
margins? Very last S3+ (brand new) they were selling for around 200USD and S5s is much cheaper in production
yes but the s5 is twice as fast and uses half the power.. so that means its worth twice as much. :/
I don't know if I go with the logic on this. It also depends on hashrate of network when you get the product.
Twice as fast with more energy savings does not always equal worth twice as much. There are a LOT of variables.
