Let me explain 2 reasons your numbers are astronomically off. Obviously, you’ve never gotten 100 players in a month, so I’m not sure why you sound so sure of yourself.
First, most places have a tiered payout structure. You may get $300 per player at the 100 player mark, but it actually works like this.
first 20 people = $100
next 30 people = $150
next 50 people = $200
That comes out to $16,500, a far cry from the $30,000 you wanted me to “do the math” on.
Also, clickthrough rates are usually very, very low. Even at 1% CTR, that doesn’t mean 1% will sign up or that 1% will sign up and play.
Your numbers are just off, WAY off.
