At the end of 2017, it looked like Bitcoin was just one step away from replacing regular money. All of a sudden this digital currency was what everyone needed. If not this one, then one of its crypto-siblings.
Seriously, what was that? Where did that come from and is it gone now? More importantly, why is there such a big controversy about it? When digging into the subject I quickly realized, that my view of it simply being digital currency was extremely naive. Interesting about cryptocurrency is not that it is digital-only-money, but its decentralized character.
As such it is an attempt to undermine the entire global monetary system. It is a direct attack on the authority of central banks and governments. Sort of rebel money, anarchistic currency, if you will.
