Central Banks Buying Bitcoin Because it Can't Be Stopped

The way I see it, the central banks have 2 options, either regulate the crap out of crypto or buy it up and control it by holding the majority of it. Ever since the silk road was shut down, it seems like the government realized the potential of bitcoin just as much a threat if not a greater threat than the silk road itself. Why would the court rule life in prison to the alleged silk road creator Ross Ulbricht? It seems to me they needed to win that court case at all costs, to seize the bitcoins more than anything then "auction" them off, with undercover federal agents buying them up with unlimited resources. Think about it, if you were a central bank with unlimited resources and there was a threat to your existence, you would either push for the government to regulate it and it's exchanges or just buy it up and use it to your advantage. Just like the US dollar was backed by gold, there was a store of value backing the dollar and now with the looming collapse of the USD what better asset to run the world economies that bitcoin itself. Another explanation as to why there are so many forks going on right now; bitcoin cash for the Chinese central bank, Segwit 2x for the US central bank and who know what bitcoin gold and bitcoin will be used for, we will just have to wait and see how this all plays out, but it seems like to me that these hard forks are political moves for bitcoin and it's dominance to be the currency of choice after the fiat collapse.
