Hi Claymore, THanks for the update. FIne work. Its great that u can regularly improve the efficiency and therefore profitability of ur miner. Its my misfortune to live in a place where power costs 0.30 per KWH, which yields no profits for XMR mining

2020 h/s @ 550w gives me less than 2 usd profit per day at current difficulty and market price

I guess everybody else who is mining XMR has lower electricity cost than I do, or, has better efficiency than I do, or both.

But in case there are among you who don't have idea re ur miner's profitability, I strongly urge u to find out. It might actualy be more economically sensible for u to buy XMR than mine/sell it. XD

(to elaborate: if u r mining at a loss, then presumably u are mining to hold and sell at a later date when price improves, thereby delivering profit to ur mining operation. but u can simply buy XMR and hold that instead of mining it. in so doing, u provide buy pressure on the coin which can actually cause the price to increase)

Cheers!
