“You don’t need a blockchain” is the new “You need a block chain” article.
I’ve lost track of the number of organizations and people I’ve talked out of a blockchain solution in the last ~6 years that I’ve seen Bitcoin as more than just a cryptocurrency.
My entry-level question when someone tells me that they want to start their own cryptocurrency:
Are you OK with people buying drugs with it?
If the answer is No, then a cryptocurrency is not their solution. Not because people will buy drugs with it, but because if the creators can control who buys what with their currency, then it’s not a cryptocurrency.
