I have no reason not to believe you. But, base on what I've heard upto now is that mining for Bitcoin is a lost cause,  a private person whose invested,  as you said ~ $4k will no longer earn a decent return, and that buying bitcoins from the exchange is the better way to invest your money...if you are a real life miner, whose actually and currently getting bitcoins from mining, and come out ahead of buying bitcoin from the exchange-  then I am all ears !! I would like to learn how you are pulling it off ??  Please PM me if you are a real deal !

I would love to see the real  cost vs benefits of spending $4k in equipment rather just buying bitcoins ?
