Cryptocurrency was started as a means to buy and sell through the internet. Once blockchain technology was released to the world it opened up the buying and selling worldwide and for anything, whether legal or illegal. Law enforcement has been busy trying to follow this trend because of the dark web. The selling of human trafficking to real underworld activities began.
But there was also the light side of cryptocurrency where one could buy goods for instance, real estate, food, clothing and not have anyone know what you are buying. No tax, no paper trail. Sounds like the good ole' days of the 1800's when there was still free enterprise, where one was free to buy and sell under their own terms.
What do you see as the future, good and bad, coming from cryptocurrency?
