Very informative. On average if you're in the top 100 you're selling at least 1000 copies a day (he says when Enigmo was on top it was selling 18,000 copies a day.
Folks who STAY in the number 1 spot get $250,000 to $1million in sales.
On the low end devs make $50 to $100 a day.
Decent-good apps that don't make top 100 make $100 to $1000 a day.
