Well, what can I say, first let me say that crypto currencies have changed the world or finance, have and still giving jobs to the jobless, providing for a lot of families that by now, would have probably not have a means of earning, millions of people have lost their jobs around the world, and crypto currency have mitigated the effect that would have had on the world economy and humanity in general.
For example, I currently have to major source of income, and that is my little business and crypto currency, the business, I started it with money I made from crypto currency, and today, I am happy and comfortable with my family, earning from my business and crypto currencies together.
I envisage a world where every home will be into crypto, not just for their financial stability, but also for their privacy.
