What is your opinion: will btc become a currency with which you can pay in supermarkets, subways etc?
Or will it remain a crypto-currency used mostly in the Internet?
I believe bitcoin will become a currency that will be use in supermarkets and other stores. Though it is not that popular as of now especially to those people that are not inclined to high technology, it is slowly adopted by some companies and somehow time will come when these people will be aware of its existence. Bitcoin cab be used now in reloading, paying the bills, purchasing flight tickets and other things so it is slowly use as a currency same with fiat and not just a crypto-currency use in the internet.
I already use it in supermarket for buying everyday goods because I have Bitcoin debit card so that makes it much more easier. I also pay the bills and I have to admit that I prefere paying with Bitcoin, it makes me happy
