There is also a chance that FBI actually didn't get the money, but just claimed they got the money back so that they could basically just act as if "if you try to ask for ransom from us, we will catch you and we will get our money back and throw you in jail" so to speak, hell it could be ALL a fake situation, this is FBI we are talking about, these guys (along with NSA and CIA) overthrow whole governments, you think they would be just willingly pay ransom and be fine with that? Of course they are going to make a whole deal out of this. I do not know what really happened but it smells fishy in here and I do not know what it is exactly.
Let's hope that they do not know a method where they can reach wallets because even though I know it is technologically impossible, I still fear that if they ever get their hands on a method like that, they could empty any wallet whenever they want claiming it illegal.
It was a good move by the US,because by such things some country banning of bitcoin.So it should be done by the US.This thread the person who involve in ransom by using the bitcoin.So by that only good people use the cryptocurrency.This further increase the price of bitcoin to the next level of price.All the countries should take care of such movement in their country.
