Why robbery?
Yes, because there are scams taking place in a way of ICOs but there are committees being prepared to restrict all those bullshit scams from spreading their greedy projects amongst public and literally loot their hard-earned money in the way of investments. So, stop being worried about such happenings.

Will it change the world?
Once again, yes. It is already changing the way people used to think about their finances. Money management on our own is the new thing Bitcoin and other cryptocurrencies have taught us as well as it is the new dawn in the field of cryptography as well as developers are now learning new and better things daily and are making more advanced and feature-equipped coins.
