I think that one element in all societal/money systems that will always lead to its demise and fall (As every currency has failed) is the element of the human animal. The desire to succeed at any costs still is latent in all humans as they are sentient versions of any mammal out there that will do anything to survive, but with hands, internet and a consciousness...
I love Steemit and worry about it and also know that 'the powers that be' will not want any currency to go against their hieracrchy and if they have the 'money' to infiltrate any new form of money with 'people' they will succeed until something outsmarts them or outbuys them...
Interesting experiment this human race, eh? @kevinwong
