I'm confused, if I visit tradeblocks mining speculation and plug in the numbers for the SP20, even if I enter the diff increase to a number 1 it still doesn't profit anything. Are people actually ordering these SP20's on the hope alone that BTC will rise or something? It is the weekend again, so I have to post one thing about extraordinary price gauging. At least I'm able to buy BTC while it is so cheap. And if all this "hope" is here, then maybe it will increase one day late next year.
