Well, George Soros is going to buy bitcoins, he would not go in and do it all at once.
I don't think he will start buying, especially if we think further; only dumb money buys the news. Soros has likely bought himself tons of crypto already, and perhaps even shorted the market from the top not that long ago. People on internet can make fun of him as much as they want, but he isn't stupid. He knows how to play this game, especially if he has been observing this market for years, which I am pretty sure of he has. 
Plus when they say they are going to 'trade' cryptocurrencies, it doesn't mean that they are going to go long. Soros especially has made a lot of money going short. 
Correct. However, going short is too late now, it would be a stupid and very gambling-like move. Going comfortably short should have been be done in December and January. There are different market phases, and each market phase requires a different approach. Him having made tons of money by going short doesn't mean he goes short on everything, especially not when it comes to crypto in current stage. It's adapting to the rapidly changing situation.
