200K BTC in Bulgarian reserves? Unfortunately no
There were some news articles posted claiming that Bulgaria is allegedly sitting on a vast amount of BTC wealth which it is holding in reserves. The country acquired the 200,000 BTC during operation PRATKA when it seized the cryptocurrency from criminal enterprises in Macedonia, Greece, Romania, and Serbia.
It appeared to be fake news.
Authorities didn't seize any bitcoin, they only found evidence that a 'criminal group' moved up to 200K coins as part of their activities. Source:
"It was determined that the members of the organized crime group invested the money obtained from these illegal activities in bitcoins, around 200,000 being discovered in the virtual space"
And it's an article of year 2017 by the way.
