Even if people will start making a plastic cards in different countries you will not have a chanse to pay with bitcoin cause it's illegal, better to leave bitcoin now and wait when it become legal everywhere.
There are countries that bitcoin is ban but most countries have embrace bitcoin and companies there are now investing and making a move for local user of bitcoin to used their bitcoin locally.
There are few countries where Bitcoin is Ban. but it is temporary. I think on people demands, Government has to lift this ban to allow people get the benefit as all other people of different countries are getting. So, sooner or later we are going to have bitcoin as legal definitely.
That's impossible, corrupted Governments will never make it legal, and if they does then they will loose all their power and control that they are enjoying on fiat money right now.
agree with if they legalize bitcoin of course it is tantamount to killing their own local currency? because no country wants to use foreign currency in their country. so it will be difficult for bitcoin be legalized sector in certain countries.
we have to be patient to spending with bitcoin in store offline
i don't think bitcoin will ever replace fiat and people will always keep using fiat besides the government will never give up control over money and printing it anyways.
but the legalizing bitcoin is another matter, people are already using bitcoin and they can not do anything about it so it is better to regulate it to be able to control the action better,
