Governments all over the world are desperately trying to control cryptocurrencies as they think it as a medium which can challenge their monopoly on economic matters because money is the key of controlling the public. Government controlled money (fiat currencies) are meant to serve the powerful, elite, super rich people while in some way they are rendering poor to poorer. Governments never like to lose control over the masses. However, there are lots of scams happening in the name of ICOs and cryptocurrencies. These scams and fraudulent acts will give the governments to take the matters in their hand and subsequently crush the system which challenges them. Google and Facebook are doing exactly what powerful people want. Yes, I agree that we need a decentralized search engine which can solve the purpose of keeping power in the hand of general public instead of a few rich people. After all necessity is the mother of invention.
