I can understand a little of the economy, but they say that in the state of money as much as gold, and this is equivalent to the entire production on the market. And then what to do if someone wants to replace all currencies in the bitcoin. I have little faith in it. Therefore, better salary in dollars or pounds.
Obviously you are right bro. Bitcoin mode payment will be much faster reduce the charges for the companies who are all paying for us So there is opportunity to get a nice wage for our work. For all things its needs to be centralised with our government.
But you can have a bitcoin backed debit card, problem solved
With a Bitcoin related debit card you can alternatively "spend" your coins, but all that happens is your coins getting converted to fiat, and with this fiat you can complete the purchase. From that point of view you can just skip this card and keep using your fiat in your daily life. It's not a must to be able to spend coins. It's an optional choice.
