Just some speculation...

In this order as it is going the last 6 days, it seems that we double in 7 days (including the day fallback).
This could mean 35 € cents end of the month....

Off course, it could go slower, but it also can go much faster, as seen last week, when the snowball goes....
It is a fact that it will grow hard until the awards Citi at 2nd october!!
