Generally speaking, all governments are concerned on Bitcoin and cryptocurrency and that is why many passed legislation or laws on the trade, use and things surrounding this new "beast" so this is not just specific to the USA. Just look at China and how it was able to almost fully control Bitcoin because the government is thinking of using the many possible benefits of cryptocurrency for its own ambition. The government has all the power to make things burdensome or easier for any industry and at this point in time many people in the governments still are wary of the effects cryptocurrency can have on the global economic system so some of their actions can be hurting this industry.
