I know in "Crypto" profit is god. 
But Folding for cures is one I will continue to do if cure coin value is zero.  People doing the SETI thing don't get Alien coins and they still do it. 
CPU cylces to cure diseases on planet earth, are much more plausible and relevant to humans beings.  More so than a stray, hiddieho neighbor, from an extraterrestrial.

Who knows, the disease you help cure today could save yours or your great grandchild's life. 

On the flipside,  If we do make contact with aliens.  They can come cure everything, and save us all from... each other?  After all who wants a bunch of sick and dying slaves/livestock?
