The miner FreeBitco is using mines Monero, not Bitcoin. FreeBitco then sells the mined Monero for Bitcoin and pays you in BTC. That is why when the price of Monero rises in respect to Bicoin, you will receive more satoshis for your mining.
Here's an example:
Case 1: Monero's price is $100, BTC's is $5000, so you earn 0.02 BTC (2 mln satoshis) for each mined Monero
Case 2: Monero rises to $200 and BTC drops to $4000. You now earn 0.05 BTC (5 mln satoshis) for each mined Monero
Case 3: Monero drops to 60$ and BTC rised to $6000. In this case you earn 0.01 BTC (or 1 mln satoshis) for each mined Monero
As you can see from the example above the exchange rate of Monero to Bitcoin can greatly influence earnings from mining.
Thank you for explanation!
I left my work pc mining during the weekend from friday evening until Monday morning and it earned 5265 shatoshis.
Be careful, dont burn it.
Is mining working in sleep mode? Or you left your computer all turned on for that days?
I hope your boss will not punish you because of mining. Or does he know about it? Anyway, be careful
