Fiat money will exist as long as countries and governments want it.
But crypto currency on the free market will be a market that people can use in several ways without inflation from government agencies. I want to say that the krypto currency is the people's money.
But, of course, the government wants us to pay taxes on our profits on it.
So I'm sure they are looking for good solutions to manage to collect taxes on the use of the crypto currency. And taxes must be paid for the society we live to be able to exist. We have only seen the desire for what the currency can do.
It's more than just an investment, it will help many people who live out of almost no thing where corrupted leaders take the most from them.
The world is changing due to the crypto currency, but it will take time. 
the ability of the token for the community in bancor protocol makes me think twice maybe central bank use crypto for reserve in the future and issue a tokenized version of local currency just like tether to make sure that evreyone pay tax :)
Yes, think your thoughts are correct.
The authority is working with it otherwise they will not be able to claim any taxes in the future in order to be in control
