Realistic earnings
Typical user. Top performers can reach $1,000,000/mo.
These numbers assume a moderately engaged audience. Most affiliates earn near the lower end — high earners are the exception, not the rule. If a YouTube channel or Telegram group is promising you the ceiling, they're selling you something.
