While I'm fairly new to cryptocurrency, I like the idea of a currency that isn't attached to a government and that in the future you won't have to worry about the type of money you have when traveling to other countries because you could pay with cryptocurrency or use cryptocurrency to get a currency out of an ATM. I believe the future of doing business will be with cryptocurrencies.
In the coming years, many changes are going to happen, like the mainstreaming and optimization of solar power and electric vehicles over fossil fuels. Solar panels are becoming more and more efficient and less bulky and expensive, and electric cars are becoming more efficient and less expensive as well. Companies like Tesla are revolutionizing energy and travel.
While the future of economies and energy is bright, we have many battles to fight. The fight for freedom of speech in a world becoming more and more "politically correct" is an ongoing battle. Donald Trump (The least politically correct man alive) can't be the only force fighting against SJWs in America, he has an entire country to take care of. We need to use logic and reason and our voting power to get Social Justice studies out of America.
