One of the many reasons why many big economy nation are rejecting the idea of Crypto-currencies is that they want to bring this industry under a centralized government of their respective nations, so that they can again mint an industry to finance there luxuries and eliminate any competition either through means of corruption or by force.
One of the ways to use this novelty is to link crypto-currency to major world issues and using it to improve the living conditions of Humans worldwide, those who doubt me, guess who is the US president and you know how he got there by manipulating the youth and addressing the issues that impacted that generation.
So if a orange guy who's a blatant womanizer can become the president of the biggest economy in the world by addressing issues that affect the general public, Why can't we crypto-currency investors invest a small portion of our earnings in the issues that affect the world and mount pressure on the global leaders so they can't shove the idea of crypto currencies under the carpet/
The issue that I would like to bring up is the use of plastic, there is a breed of bacteria that eliminate the problem, here is a link describing the bacteria's work. http://theconversation.com/how-plastic-eating-bacteria-actually-work-a-chemist-explains-95233
So this is currently getting major media and political interest so if we target this than these government won't have a chance to eliminate or ban the use of crypto in their respective countries since the governments are elected by the public and if we win the support of public there is no way that these publicly elected governments can ignore us.
