Bitcoin is the worst waste of resources and energy in human history. It is solely used for financial speculation, with no genuine utility.
This is a call to ethical hackers: through targeted and repeated computer attacks, we could undermine the confidence of speculators and burst this irrational and destructive financial bubble.
Keep in mind that unless you take down all cryptocurrency, speculation using them will continue (yes, even the non-minable ones, people spend tons of energy trading actual countries’ currencies too, and blockchain is inherently much more energy intensive than regular electronic currency). Just taking down bitcoin solves nothing, will land plenty of people in prison, and just further vilify technology activists in the eyes of society.
