Here's a theory on the story about Russia preparing to buy $10 billion in BTC.

There have been two sharp downturns in BTC (and everything else's) price over the past 3 weeks or so. If Russia is preparing to invest in February and they had the ability to do so, wouldn't it make sense for them to prep the market by triggering these coordinated dumps to drop the price?

I think we're on the verge of something big in the crypto space.
