My goverment forbid bitcoin usage because it can be use for money laundry ( advantage for terorism activity )
So it has small chance for my goverment for bitcoin usage as the result bitcoin popularity can't grow like EU zone
I think only a few politicians in a country know about bitcoin, I think even though they knew about bitcoin, they certainly will not take the risk to launder millions of dollars in bitcoin because it is very risky
One thing I want to clear you that bitcoin is not risky, and I think no one know that who is using bitcoin and who is not using it, as bitcoin is anonymous, maybe more politicians use bitcoin but we do not know about them. But at the end, they are contributing to a new technology which might help a common citizen with bitcoin's investment characteristics.
The thing is it's not safe either, maybe our definition about safe and risky differs because we are making decision base on how valuable bitcoin to us. But I would stand with my opinion that bitcoin is risky as for me it's more on an investment than an online currency.
