Maybe they think realistically by investing in gold or silver. Anyone who does not really know the value of bitcoin and doubt it would prefer gold and silver. As for those of us who already understand will choose bitcoin.
It might be their own strategic planning. We cant just intimate what would have been planned against this strategy. This might be a chance for them to lose their value in crypto world. Because later on, when bitcoins would be the only supreme factor of categorization and nations are measured accordingly, then they will lose everything. So better for them is to make good moves towards this side too.
