No government doesn't like money and the cryptocurrency industry is worth billions .Bitcoin ain't no threat to no body, some body in China farts and a few hours later a big storm hits crypto, they place their agents as speculators into the Bitcoin's society and they are essentially controlling the market, they are not in control of the supply but they are manipulating the price.

One can buy the entire bitcoin if each and every user sell the bitcoin. In reality it's not at all possible for a single user to have the entire bitcoin. I do not think anyone can buy all. Unless the price of bitcoin goes down.

It's actually funny that you say "this time for sure", I mean it just sounds comical at this point. Bitcoin is doing good and these kind of threads will make bitcoin even bigger.
And yes 450 is just the beginning.

Because Bitcoin is not a major concern for them. They will not banned bitcoin in theor country because they see bitcoin is a very advantagable thing and not negative thing.

It is true that we do not need that many cryptocurrencies as we have today. A lot of people are trying to push their vision because they are aware of the upcoming selection. Will just be hoping that this will have to stabilize in the coming weeks and lastly these kind of subject was a sort of the negative side which might create FUD in the crypto market thus affecting the market price.

 bitcoin will always have its advantages and disadvantages as well as its strengths and weaknesses, which some hackers should be aware of right now. Don't forget that criminals don't care about currencies. 

 Governments are greedy for the control and thus they will never allow anything that can cause the threat to their ambition of controlling every aspect of our life.

The banks will not offer deposits using bitcoins. Because the bank wants to earn more profits. the bitcoin value is very volatile whose price is surging due to demand and supply.
