Hillary Clinton is alarmed by the rise of BTC.
Who is Hillary Clinton that anyone in the world needs to worry about what she thinks?
If the govt knew about crypto and its implications years ago they could have stamped it out. Now, it is too late for them.
If you think they didn't know then you are grossly mistaken, because they knew and were aware from the very beginning, especially if you mean the US government. If you know who
Gavin Andresen is, it's interesting to whom he lectured on Bitcoin back in 2011.
In an internal NSA report dating back to March 2013, the agency indicated that it had used at least one source of information to target bitcoin users, leveraging its sophisticated tools to collect and analyze global internet traffic data, while also exploiting an unnamed software program which is said to protect the identity of users, reported The Intercept
Just like El Salvador, US could also try and capture the entire BTC circulating supply. And, if the US Govt. doesn't then Kremlin or other countries might.
So, the US Govt. can easily print out $1 Trillion Dollars which is not really all that much when you compare it to gold and then capture the entire circulating supply and use it as a reserve.
El Salvador is not trying to buy all the Bitcoin that exists, nor would any other country try such a stupid move that would cost much more than just $1 trillion. But let's say the US does just that, how much do you think 1 BTC would be worth then?
