Mining is like going to war, the lower your electricity rate the stronger of a weapon you own, the average power rate in China which is where the vast majority of mining happens is 4-5 cents and as low as 1-2 cents during the hydro season, which averages 3-4 cents through the year, now back to the war analogy, it's like you are going to fight with a pink chopstick whereby other people are driving tanks, so you shouldn't even think about mining at such cost.

I believe danieleither is in the U.K, and he most likely doesn't mine at a 25 cents Kwh rate, so hopefully, he can chime in and help point you in the right direction to get a proper power rate.

Also, the $50 daily thing is not how mining works, your fiat income can change by alot within a short period of time, so if your set-up makes you $50 today, by next month it could be $10 or $100, your income in BTC is also most likely to decline since mining difficulty in the long run only goes in one direction which is up
