yes my numbers are real. No assumptions.
All my customers know they will pay at some point.
I like your approach and I plan to do it as a last resort. my point is that I expect at least 30% churn rate when I start charging my customers.
So I prefer to reach 1000 or 1500 sellers signups before starting charging.
$25 is too much for an emerging market like Egypt. I prefer to charge $5 or $6.
