Could someone please explain what would be the Maximum amount of money you would be able to earn on a daily basis, IE: Shops would be x amount and then if you didn't use MB you could earn from a Championship game, a Trophy match and maybe a defense or 2 in the GvG.
What would be the Maximum amount per day?

Maximising Snack and Goodies gives 17,933,760. Maximising training games at L48 gives 1,265,000, not sure if this is higher at L49. Then it would be down to how many Champ/Tourney/GvG games you play in a day, maximum per game is 5,644,800.
Of course, these will change with the next level upgrade.
E&OE
ps On the days when the Champ resets, you can double the return from training games.

Shhh! Don't tell everyone!

well to break it down you could play

5 training games = $1,26500
1 league game = 5,6,44800
2 GC's games =11,289600
1 tournament game 5,6,44800

totals 22,705,700 (if you had a max fanbase for all games with max ticket office this is before adding on your snacks and goodies shops )

Snacks 189,00 x10=1890,000
Goodies 379,00 x10 =3794420

which added together totals $28, 390,120

however depending on how fast the snacks and goodies shops reached max capacity you could potentially gain more if your talking over a 24 hr period if you was online a lot. I believe the snack shops fill to max capacity in about 4 -5 hr not sure on goodies but believe it's a little longer . Also I haven't taken into account GC defences as you could potentially get challenged up to 50 times but obvs that is highly unlikely.
