Bitcoin and the War on Cash

In two thousand 18, i did a personal experiment where i i wanted to see if the war on cash really existed. Two thousand 19 though, i started traveling the world and realized that electronic payment is much more prevalent in most of the world than it is in the united states. Now, another thing that really impressed me from the conference was that i don't see any major problems with with bit coin that haven't been solved or aren't being worked on by some of the smartest people in the world.
