With 25 000 new bitcoin addresses created today and new money keep flowing into bitcoin market it's clear that bullish trend is very strong, but do you think creation of new addresses is a valid metric ? Creation of a new address doesn't automatically means that the user is new, I have many bitcoin addresses.
not this is not a valid metric, since most of bitcoin user create new address when they should receive a payment.
a good instrument could be "how many addresses own at a certain amount of coin in a specific timeframe" since a certain level it means more people are joining the network.
but even this isn't the best metric since various addresses could belong to the same ownership.
