It's easy to point fingers, but a government shouldn't gamble. It has a responsibility to its people. To be fair, most governments have done things far worse than gamble with 1 to 2 billion, but that's beside the point. What if Bitcoin had gone down in value? Imagine the people who were going through difficulties. Public services that needed more funding that wasn't there. That was a lot of money that could have been used. And people would have every right to blame the government for making that decision.

Furthermore, when would they sell it? Would now be a good time? What if it keeps going up? It's easy to know the lottery numbers or the result of a sports match after it happens. Before, it's just a gamble.
