This, absolutely. I'm actually surprised the government showed their hand so soon. There must be a lot of money in Bitcoin already. The government WANTS people to go 100% digital with their capital. It is infinitely easier to track digital money. Bitcoin is something they're against because the anonymity factor. I won't be surprised if we see some legislation to block or inhibit anonymous digital currency.
Let's not forget that the US will really want to "own" or be in control of any significant digital currency. Since the US dollar is the world reserve currency, the US wields unprecedented economic power on a global scale. Any currency that has the potential or shows signs of shaking that up will be on the radar for the US govt and the Fed, as controlling currency is the means by which one can control the economic destiny of any nation(s). As we saw with Egypt, for example, several years ago. A simple change in US monetary policy can result in the overthrowing of foreign governments!
Interesting side anecdote: A person very close to me purchased Bitcoin on the stock market, but Bank of America froze the account on suspicion / risk of money laundering or general FUD. It isn't clear how much of this was due to the bank or the government, as they are in bed together, but it prevented this person from being able to trade Bitcoin in his account anymore. Sadly, had his account not been frozen, he would have doubled his money.
