So as to do this,  we must finish povery very first then alter the education about cash and finances. Not only that,  we have to force technology-illiterate individuals for doing things. As dreamy as it is, it can't finish well

Very interesting project .I like it .

This is something that European union has tried and partialy successeded, to use 1 forex for those fellow member states. But still you will find issues so I don't believe it's possible for entire world to use just one forex. Many countries think about forex as part of their sovereignity then one that economy relies upon therefore it is hard to abandone that.
