1) How do people think that bitcoin is actually anonymous? You would have to buy them with your debit card/credit card in which banks have your information... why would you think that this stuff is actually anonymous and could be used in such a way?

2) How many people develop bitcoin? If it's a decentralized currency then if these people control how the currency works, how would that make it decentralized?

3) If it is a currency that can be used in a sort of anonymous way, then how can governments regulate it in a way to make sure that people aren't funding bad organizations like ISIS and drug lords?  "Harpua" has told me about what silk road was and the way the darknet markets work, but how can this be prevented?

4) My dad works in a government facility where he deals with high clearance documents in a high security facility.  His organization has just been recently hacked by the Chinese government and lost dozens of top secret information including SS#'s, locations of the homes of workers, basically any personal information about the workers of his business and his families (which includes me). How can cryptocurrencies ever be a secure enough form of transactions where governments and top notch hackers can't just find a way to hack into the blockchain database?
