Why are you recommending bit-x? That isn't the best one as I think. Try some long-lasting sites, like cex.io. They are online for about a year I think. Also they have records of which block they exactly mined, not like some other sites (like bit-x).

i would recommend your pbmining . i dont know whts wrong with people they saying its a ponzi site. but i`m getting paid from a year without any problem however only once or twice i got my payment late and less money but now its working greeat . just an advice.
