Cryptocurrency and blockchain can kill?!

You need to be very careful when dealing with cryptocurrencies or playing with blockchain.
This world seen a lot blockchain and cryptocurrencies followers same as enemies since this technology showed up on earth.No one knows what else it can bring to the world apart from an innovate technology and its unknown usage.One thing is sure ,it looks like IT technology developers started being too dangerous for politicians and bankers and overal world economy.
In South Korea 52 years old Jung Ki-Joon,Cryptocurrency Regulator who was coordinating cryptocurrency legislation was found dead at home and died of some unknown cause.Mr.Jung was working on illegal activity on crypto trading market and he was vowing the government to respond to these illegal activities as cryptocurrencies are not deemed legal.The thing is ,South Korea has a big impact on crypto valuations as nearly one fifth of crypto trading comes from there.Maybe mr.Jung was traing to stop that what the government want to do and make a lot of money from it.Maybe he was the problem for government and they 'took care of it' ?! S.Korea is known from its crazy actions...who knows hat really happened and what else can happen yet....
I wonder will crypto and blockchain can really bring a war in economy sectors all over the world as it can be used in many ways at yhe moment and there is no clear regulations of using it yet?
