With the likes of government , NSA ,banks etc..Could they coordinate into creating their own crypto to defeat Bitcoin?
Creating something like 'Legal Bitcoin' , invest and pump, make it succesfull? Make markets aware
Maybe even create their own cryptography where they could still be able to decypher code if they needed to?
Yes of course. We know already that governments and banks has billions or even trillions of funds to start for any projects they want to create but the question is, How about the community, do they really like to support centralized type of crypto? Though I know one coin that is the best example for this matter and it is no other than Ripple (XRP). Look at the status of Ripple now it supassed the MarketCap of Litecoin and is listed as top number four coin in the market with high cap. It always depends on the community if they are investing to the coin banks and governments created. Some issues with such projects are safety and privacy which investors are looking for before investing because they thought there are ways banks and governments has to use their own cryptography to have an eye with our funds since it is centralized.
