Let's see...
Network operator gets €0.12/kWh
Provider gets € 0.168/kWh
And in the daytime hours i mostly get power from the energy cooperative network, a community of mostly private solar power providers, where i pay Q3 average market prices (€98,20 per MWh equals €0.0982) + €0.025 excl. taxes, so let's say €0.148 incl. tax, while i sell a kWh for market price + €0.012 (plus tax), which would get consumed mostly by the miner (free power).
In the future the government wants PV power sellers to also pay network fees, so the less i have to sell power, the more efficient for me.
Still this would average to about €0.27 per kWh needed from the network, which would be about halved by getting free power from the roof/walls of the house.
Let's say €0.16 to stay on the safe side, which equals about $0.19, so slightly less than 20 cent power.
And if the Euro gets weaker again (or stronger Dollar), i'd be operating the miner(s) at a loss.
