That&#x27;s my main issue with bitcoins (aside from how they&#x27;re marketed to anyone; it is most definitely NOT anonymous!).<p>Instead of &#x27;proof of work&#x27; it should require actual, &#x2F;useful&#x2F; work.  I think it should be a mix of work &#x2F;types&#x2F; to promote general purpose computing, instead of ASICs.  Imagine if a comity decided, and the owners of existing coins voted on, what work was worthy of being included.  Folding proteins for medical research, SETI, attacking DRM&#x2F;bootloader encryption keys... things that benefit the world.
