My line when discussing crypto is of evolution
As everything around us evolves … I GIVE EXAMPLES OF engines, phones, computers … etc so does the concept of currency from gold based monetary systems of ancience through american wild wild west banks with a clerk filling ledgers finally coming to computers that relieve the accountas of their job which is the most expensive part of any enterprise - human labour .
Thus as everybody is looking ways to cut costs of their business so eventually money will be hjandled by computers also i theorethise that future currency will be energy .... btw if any one cares to read my post plese comment why you think that future currency could be energy if not i will explain my point of view later and / or comment
