So you're saying that with all the investment into crypto-currency development, and a techonology that did not exist in any form 10 years ago, that it is impossible to scale?

You are saying it is impossible to create an improved form of crypto currency that solves scaling? Even with 10's of billions of dollars being invested this year into their development? People are throwing a lot of money at this technology. The stakes are incredibly high. If someone does find a solution and creates a form of crypto currency which can operate at scale and do so for cheap fees, they'll become at least a billionaire.

On top of becoming a billionaire, a crypto currency that was able to transact at scale, securely, for pennies in TX costs would fundamentally change the world.
