I began my career in the tech sector with one of the largest telecom companies in the world. As an in-house device tester and Go-To-Market analyst I had a front row seat in watching smartphone technology change how humans communicate with each other, and how we connect with each other. The internet made the world smaller, smartphones made the world so small you could hold it in your hands or stick it in your pocket. Looking back at the effects of "technology" on humanity over the past 2 centuries I can't, at this time, recall an instance where a technological advancement as disruptive and accessible as Blockchain and cryptocurrency failed to AT LEAST achieve it's intended purpose.
There will be many failed projects and ideas, and the established "powers-that-be" will fight tooth and nail to suppress the change, but in the end humanity will have a new way of exchanging value from one individual to another. Cyrpto will prevail.
