i know it is too early..
but i'm following notes subscription on https://blockchain.info/it/charts/received-per-day?timespan=30days&showDataPoints=false&daysAverageString=1&show_header=true&scale=0&address=37X8DHpfiimB7PU5y35rfBcg5Vxj2R6umL

averaging btcs/day on the graph i can see 30btc/day.
if each day are sold 5 millions note, i think 30btc/5 millions --> 600sat each note.

testz,
it is this correct?
or not?

thanks
