Great shopping. I buy a motor bike from super market 2 month ago. But not Bitcoin but Bitcoin earning cash money. Our countries don't accept bitcoin directly but many people use it. I convert bitcoin in USA dollar.
Yes there are a possibility coming back bitcoin fever. Already there are a lots of currencies in cryptocurrency market caps. I think bitcoin fever coming back soon.
There are many countries accept bitcoin as legally because those countries people's realise the value and importance of bitcoin. Japan, Netherlands, Ireland, USA, Canada, Australia, New Zealand, a major portion of India, bitcoin eco countries.
Which countries accept bitcoin as legally, there could be possible bitcoin as a payment system. I don't find any countries where Bitcoin directly use as salary payment.
