Look at all the fortune tellers battling it out. IF you asked someone a few years ago if Bitcoin will go to $250 almost everyone would have said NO. LOL Just keep mining fellas and stop arguing.
Bitcoin isn't at $250 right now. It's not even half that. It wasn't even at 250 for a couple of hours.
Don't mine because you expect bitcoins to go up. Just buy bitcoins instead.
Lets say I buy a 7970 for 400$ now.
It mines at 700mh/s. We have a price of 110 and in one year, Bitcoin goes to 200. Profitability declines by 60% or more.
You have 727 dollars when investing, ~ 1500 after one year of mining and not selling bitcoins.
