Bitcoin holds negative image in the minds of people and they think that bitcoins is used by criminals and it is used for illegal activities and that is the reason its not getting support from the people and government.
This is one of the reason why other countries doesn't want to engage and start using and adopting bitcoin.
What comes to their mind is that it can harm their economy and they will push their people to start engaging into shady transactions.
They really don't understand bitcoin as it is not just only for those people that had been using it for their illegal deeds.
But soon, they will understand that bitcoin is a good tool to help their economy and they will start using it.
Right, even the government they cannot see the significance of bitcoin to the people they are just into negative side of it, they do not look further out of it. But we hope someday things will be okay and soon to implement as the world currency. Those shady transactions and some negative aspects of bitcoin must be erase into their minds.
