Ask yourself why anyone would dedicate a considerable amount of their time to passionately ranting about something that they believe is doomed to failure.  For hours, daily.  Some have been doing it for months, years even.

I mean I'm pretty sure that, sadly, Mars One won't have anyone arriving on Mars before 2028, as is their stated goal.  But I'm not going to spend thousands of hours trolling their forums because I hold that opinion.  In fact, if I'm proved wrong I'd be thrilled.  In the meantime it, naturally enough, simply doesn't cross my mind very much.

So we turn to Bitcoin where the forums are trolled quite disproportionately and we ask ourselves why these people are here.  Consistent, vociferous and prolific.  Why aren't they getting on with their lives, checking in every so often to see whether they've been vindicated?

One has to wonder.  And not long after you begin to wonder you develop some circumstantial suspicions, shrug and move on with your life.  Let them waste theirs - don't let them waste yours.
