it is speculation, but if some of these tokens/coins can achieve half of what they aim to do they could be revolutionary. I think of all the things in our society that need to be more secure, and all the people whose local government's currency is not to be trusted. 7 Billion people have a lot of needs and these innovators are trying to answer some of these global problems. Some will survive and some won't. However, it is hard not to make money right now with current conditions.
