over time as things move around you can update them tags. and see more coins with more tags as your data grows over days, months
and then know how much is peoples bottomline / break even. to know what the communities attitude is to a certain price based on % of the communities bottomline, that way by marking each utxo to have a 'price' you know what it is not going to sell for as that would be stupid and a loss.
i done something similar but simpler based purely on the UTXO set that moved in the last 11 months (while prices were above $5,800 bottomlines) and seen over 65% of UTXO's got spent within 11 month. even though my data did not involve coins that entered /exited an exchange. but by purely changing hands people normally (psychologically) self value their coins at the value they change addresses
but having a better metric of marking the coins with a price they exit exchanges at. gives a more precise depth to what 'value' people put as their bottomline refuse to sell below price as they have preferred to exit an exchange instead of keep it in to sell it
This is smart. It sounds legit to assume that people usually deny loss and hold tokens instead. it also explains why the transaction volume in exchanges shrinks that much compared to the beginning of the year.
We can add this price tag to each transaction, in addition to the exchange tag for the address. Seems at that time we could identify some good traders.
