PB Mining vs Cex Io

[darkphantom934]

Cex.io is treats GHs as commodities, so you can buy and sell as you wish. PBMining is a bit cheaper, but you're locked in to the GHs you buy, like a contract. Cex.io also has very good monitoring of GHs as well as payouts whenever you like, while PBMining pays out weekly.

Personally, I prefer Cex, but PBMining looks like it's getting popular.
