Bitminer.io is a mining site for bitcoin and it promised to earn you bitcoins of 0.15 per day and the affiliates earns you 50% , so this attracted me to register but not invest yet because i am on the thinking that i have to try this site first and see what happens .
But at this moment when i feel that i have to withdraw my bitcoin , theres a new findings that they say that i have two accounts which are free and i can only have one free account then the other have to be upgraded so i think this site is so close to scamming or its really a scam. I already encountered such a kind of scheme , where you put a certain amount of bitcoin and they will double it , this one is different in the sense that its mining but if you search on mining you cannot earn that much in a day for a bitcoin mining site.
So sorry for the referrals that had registered on my links with this bitminer , just keep on reading my post and bitcoin system had a lot for the future. There are other sites that will give you free bitcoins if not invest and earn more.
