If you're serious... epic fail, you just make everyone else's coisn more valuable

We are aware of that. We have no problem with helping other people get rich. You can thank us for our "donation" by destroying a few bitcoins

(And bitcoin can be modified for greater divisibility, so that's not an issue...)
That simply divides the bitcoins up into smaller portions. Every bitcoin that is lost, is gone for good and simply reduces the amount of bitcoins there will ever be. So every coin destroyed is a small step

Unless you can convince EVERYONE to destroy their bitcoins, you only give away money to other people.
