I see 3 main challenges for humanity

1/ how do we get out of all the slavery systems we have burdened ourselves with

2/ how do we prevent earth colonisation by one of the competing amoral alien races who seek our ressources and make us a colony (they tantalize our elites with futile tech)

3/ how does humanity finally grow wiser and get out of the current plateau

Bitcoin is the path to 1/ and helps with 3/ a bit
