Depens on the influencer.
Streamer is always based weekly or monthly, I got information for Degenerate Gambler (BossManjack) on Stake. He getting paid with RAW balance every weekly around 8,000$. So, you can estimated how much they're getting paid.
Based on hug is their fans.
That is huge for successful streamers.
Probably they will receive income in two flows: one is a fixed income from their contract with the company which hire them for streaming; another income flow is from their affiliate link. The second one will give them big income if they have huge fan base and many of their fans register accounts with given affiliate link and actually make deposit, bet on that platform.
