So right now Ripple could, if all were freed, be worth 300 Billion? That's yuge. I always like to have an idea about these other coins, even though I am not an investor, I just like to know. Actually I had never even heard of railblock. As for the cards I live in Honduras I don't believe they are of any use here.
I'll wait for your next video I found this one very informative.
Now I have a question for you, who is @thejohalfiles?
