I am mining in cointellect since 2 months. Contaract mining is fine, I've purchased demo contract and daily earnings was around 1.75 euro +- 0.05 eur.  Other time I run gridseed g-blade 5/6 mhs and i am earning aroung 1.50 auro per day. But this week something is wrong with them.  Two days ago I made withdraw in dogecoins and still dogecoins are not sent to my address. Today i made withdraw and coins was sent instantly. I don't know what is wrong with their pool but today I don't have earned nothing from my mining, yestarday I have not earned nothing for 10 hours. This is happening for first time to me.  They don't answer emails, don't know if they are busy or just don't want to bother with us...  Their software is good and I don't find viruses. I am earning around 0.30 euro per day with cpu mining with core i7 2400 with their software set at 70% intensity which loads my cpu max at 50%   I've mined in many other pools with gridseed gblade and max earnings was 0.30$ per day from WDC mining, with dogecoin i could earn max 0.20$.  I don't know what is their scheme, but at all in cointellect you can earn much more than in another pool. 
I hope they will fix what is wrong... Still my earnings for today are not showing in website, but I am mining. Thats weird...
