The last time Soros did a move was with gold and he was right again, so I would expect something happening. I think it will take 2 to 3 years but that's WS people waited with their short positions for the 2008 crash to become rich.
It seems that what you expect to happen has already happened. From the same piece linked in the OP:
Meanwhile, Soros’s fund also cut sharply its position in gold, selling off the bulk of the shares it had bought last quarter in Barrick Gold Corp., the world’s largest gold producer, and cutting sharply its position in a gold-backed ETF set up by the World Gold Council. Soros’s fund had opened the position in the first quarter, disclosing call options in about one million shares. Soros also sold off the stake it opened last quarter in miner Silver Wheaton.
The morons in the Gold vs Bitcoin thread (and its clones) would be greatly surprised by the amount of profits Soros might have made with gold in so short a time...
If they had brains in the first place, and were given a chance to find out in the second, of course
