So, if the electricity costs will be much lower than with GPU, the price of vnl will not go higher, than it's now (during GPU minning). Am I right?
Impossible to predict, maybe something else will change the market.
So what's a point to allow FPGA's minning VNL?
A lower electric bill.
that will not happen.
difficulty will go up until it's barely profitable to mine with fpga, or even higher.
that's how it works: if there is money to be made, people will come and mine, until difficulty is so high that someone must leave.
it balances itself.
Maybe the point is to secure the network.
