EOS have a plan to do it, its already have some adoption in Venezuela as payment processor and also provide micro loan for some bussiness there.
Also, its now deploying its Governance system (EdenOS) and they already have election of its president
I don't know if EOS will go mainstream anytime soon. Other top alts like ETH or XRP are more popular when it comes to payment method
Its comes to mainstream on Venezuela, its not mainstream to the world since its a quite complicated to create wallet. Nowadays its not really hard, u can have scatter on desktop or Wombat on smartphone that would make u a wallet on a click. With wombat apps, tbh its a great apps with function to surf on dApps and smooth payment with possibilites to scan qr.
