The sharing economy is just going to continue to grow, and governments will be challenged to understand and manage its implications while embracing its benefits. However, governments will be at a significant disadvantage if they wait too long and newer technologies and markets will have already been developed that do not follow traditional models. Think of the following: Uber is the worlds largest taxi service and owns no cars. Airbnb provides lodging yet does not own real estate.
How will local governments adapt to these new ways of doing business that are disrupting traditional business models? All we know now is that governments are a long way from even contemplating and accepting this new reality.
There are some advantages and disadvantages of crypto-currencies. One of the advantages of it is a new system which is based on blockchain technology with higher security for users other than that traditional models. As you know some countries banned all the services related to the cryptos but except that some governments in developing countries invest in this technology. The reason ban on crypto services in some countries is that e-payments can be done anonymously in favour of terrorism , drugs and other services. But in my opinion, in the future this currency will justify itself by spreading all around the world. Think about the knife, it can be used for both killing people and cutting vegetables, fruits depends on people whom it is used by and how? That is why many countries will accept it.
