This is what I most dont have to understand, why some countries decided to ban bitcoin and then later on, they lifted up the ban and allowed again to use. I guess there a reason behind this, in my mind, they realized later on that bitcoin is very useful in society and this does not become a threat to them.

With proper regulation, they'll be able to benefit on bitcoin and their people, so banning should not always be the best solution.
They think that it could be easy as that, but the fact they can't regulate this and I guess the reason they lifted after banning bitcoin. Even though they restricted or even banning crypto, people can keep using it without knowing them.
