Mining with CEX.IO or why do I not believe skeptics

[junglecat]

I buyed 250 GHS and realise he mines only with 16%,  84% goes for costs to cex where is logic!!!!!

U loose money 100% take calc in hand!

How did you get the 84% figure?
I don't use cex.io, but from my calculation, it seems the fee is about 30% now (the fee% went down considerably  because of the price rise in the past few days).

You are correct that the current fee is ~30%. The algorithm is here: https://cex.io/maintenance

your calculation is wrong.
current fee = (0.105 / 0.1654) * 100% = 63.5%

Yes, I calculated it a while ago and have not looked again. I should have been more clear. So it has doubled, so has the price per GH. It still isn't 84%. Assuming the market keeps moving sideways 63.5% is still very good as an electricity hedge.
