Unfortunately there are few governments in the world that abide by the willingness of the general population. Most of the politicians these days just try to get the most out of it for themselves during the period they are elected.
And of course "powerful" and rich governments are scared of cryptocurrencies and the blockchain technology because it challenges the power they have now over people.
In my opinion in the end cryptocurrencies will prevail because of the huge community behind them and the real world-changing cause behind them!
It is going to start turning into a major battle here soon I can just tell looking back on things already you can already see the gears turning.
