Here is the best strategy to earn big money with ASIC miners...
i love this ^^
and i want to borrow your time machine... i promise to give you back in a blink of an eye, u wont even notice i'm gone...

If you do it right, you can return the time machine
before you borrow it! Or will that cause a rip in the time-space continuum?
Btw, you must kill Hitler if you borrow the time machine. But everyone already knows that. It's Time Travel 101.
And clearly, nobody's invented the time machine yet since history records Hitler causing havoc. Speaking of rips in the time-space continuum, wouldn't killing Hitler cause a pretty nasty one? Of course, there's always the problem of the paradox... imagine I create a time machine that can only see 1 minute into the past. I see myself and decide on a whim that I can't take it anymore and shoot my former self. So, now my former self is dead, which in turn means I died a minute before I shot myself. Wait... who pulled the trigger then?
