I don't know what you think about it - but I still miss coin developments that have the potential to improve society on a social, political and global level. Coins that enable, for example, a global welfare system. Or which makes politics corruption-free. Or overcoming nationalism and enabling global politics. Ideas that have the potential to change society.
Or I just haven't gotten to know these ideas yet? I am grateful for every tip!
