No he wasn't, if you read his post he was talking about trading stablecoins. And even that is a real business...
I don't understand what you don't understand about it. It's very simple. If you already had multiple people try to explain this to you when you could just look it up yourself to see what they are talking about then maybe you have a hard time comprehending a simple explaination. Again, not trying to treat you like an idiot, but you do know how to use google right? You know how to type words and look up words you can't spell right? Because if you already know the answer to the questions you're asking, then what are you doing asking them? Just because someone doesn't explain every little detail to you like a little baby doesn't mean they don't know what they are talking about. And this is just the way normal life conversations work, how old are you?
But to answer your question the best way I know how.
A DAO is a coin that can enforce contracts through agreements between it's selected members or even the majority of selected members. I don't know what coin you are referring to or what each individual coins rules already are, but that's generally how a DAO works. And if you think I don't know 100% of what I'm talking about then you're right, because I really don't know 100% of each individual crypto. Because I am not a selected member of any crypto currency, nor do I know every single rule each individual coin has. So I don't know 100% of every rule and detail of how every crypto coin DAO works, but I know the general idea and that's enough for me to comprehend. So I'm sorry if you can't comprehend that, better luck next time.
