As I was a student, I wondered that only state could issue money. What if this state is corrupted? Or stop existing? I realized that it seems like all people only imagined that their money has real value because in fact, it was not so.
Today any person may create a currency and that is rather a challange than a problem. However, it seems like people trust each other more than it was 10 or 20 years ago. And it seems like all the limits are gradually disappearing. We already have smart contracts, the possibility to buy and sells goods using cryptocurrencies, and what is more important - we have a freedom and opportunity to choose what we like or not. Basically, the sum of those choices designs the future. I think that decentralized communities would win and the states in classical meaning would finally collapse.
No no its not about people's trust on each other but most people investing in cryptocurrencies even do not know the algorithm behind it, they only invest with the idea that their investment will grow one day, blockchain technology being decentralize, fast, secure and fast is attracting people to invest in cryptocurrencies but there is a also a dark side of this business so many frauds are happening which are not controllable, there must be some protocols to launch and use cryptocurrencies.
