The real value of anything is always what people are willing to pay for it at that moment.
Thus if you see DOGEs are worth 175 satoshi then that is it's REAL value.
There is no such thing as an unreal value.
I totally disagree on that. Example: If I have information that for some reason a coin will devalue, but the coin is still traded for ,say, 150, than I would not say, that the real value of the coin is 150, but lower. The value of that coin only is at 150, because the people trading it, don't know that information yet.
But if you don't want to agree on that, maybe lets not call it "Real value" but "reasonable value". If i look in ALL the Details of a coin and compare it to other coins, am i able to see through the hype of a coin and see its "reasonable" value? With Doge that is hard, because the hype is pretty much the only thing that carries the Coin.... well maybe i have my answer there.
