I don"t thing using bitcoin for our daily use is easy. Because it is not legal in many countries. We can not buy things from small shops with bitcoin. In present situation if we want to use bitcoin we have to change it to dollar or any other currency.
Yes for now we can't usr bitcoin in our daily life but till now i haven't heard any country banning the coin. Even though china is exception but if you notice japan has adopted it so we will soon see more countries adopting it if not maybe impose a tax but not a ban
if they can't stop the trend for sure they will do some action like imposing taxes instead of banning the system, japan is a well known established country if they already have integrated their system more well established country will follow especially those who's dealing with them.
Imposing tax wouldn't help much as there are already more than 100 ways on how to avoid taxes for using bitcoins. The only thing that matters now is more countries should adopt bitcoin like how japan did. As this will help the bitcoin to grow more in terms of market cap and price
