Past human history is checkered with currency manipulation and conflict..
Bitcoin and cryptocurrency has been filed with manipulation and conflict! We've seen fraud, theft, in-fighting, consolidation of mining operations, blockchain hijack attempts (in the form of forks), and more theft. There's nothing about cryptocurrency that is inherently peaceful or humane.
Cryptocurrency/blockchain offers more freedom to users. We are no longer controlled by an intermediary called a bank, we are the managers of our own financial system, if we want to be. It's in that freedom that come greater choice and control, but it also requires greater knowledge of how the system works and the risks involved.
I appreciate your positivity, but let's be honest here. Cryptocurrency is like the wild west!
