Real Market Capitalization

[a.denis1]

Everyone know the "Market Capitalization" it is not how much money there are inside the bitcoin market .
It is not the measure of the value of all the bitcoins , it is only the multiplication of the last transaction .
Anyway it seem to me possible to compute the REAL VALUE OF ALL EXISTING BITCOINS . We only need to track for each bitcoin the price ( in USD for example ) of its last transaction . The sum of all this prices is the real value of the bitcoins market.
It is clear that there are "private" transactions outside of trading markets where we can't have a corresponding fiat value anyway such computation for sure give a better index of the value of the bitcoin market.
So my question is ... exist something like this?

I'm not sure why you want to do it?
What exactly do you want to know and why?

You want to track the price of each of the however many millions of bitcoins when it was last traded?? There's no way to do this, you cannot track an individual bitcoin and even if you could you wouldn't be able to find information on what price it was last traded at.

I mean there is a case for saying that Bitcoin is worthless (market cap wise) due to the fact that there are a good chunk of coins that have probably been lost over the years. But I don't think that would really be fair, cause there is no real way of saying that coins are lost besides the fact that someone says that their coins are lost. We can't just say cause these coins haven't moved in awhile that they're lost, that's not true -- somebody could just be HODLing for a really long time.

Losing coins could also be temporary, something could come out which helps people to find their old coins, maybe they find some old papers with their keys on it, who knows.

I think this would just be a waste due to how temporary losing coins is.
