Definitely not. ATH in # of Bitcoin addresses signifies a lot but as we already know. This is not the only factor that will cause price growth. Other factors including : Supply, Demand, Market conditions, governance and regulations, mining costs and the market share. There are more factors though but these are the decisive ones. Bitcoin's price would reach a new all time high when most, if not all of the factors correlates with one another. And from the look of things, I believe we're on path for another mega run to reach ATH. That said, I'd still like to note that Bitcoin addresses ATH is an important metrics as it shows the network coverage and reach. More increase in # of address with at >0 BTC == more users == more adoption.
