About Marta
Marta works on the part most bonus coverage skips: whether an offer is worth taking once you do the arithmetic.
A 500% bonus at 40× rollover with a low maximum bet is a worse deal than a 100% bonus at 5×, and the headline number will never tell you that. Her writing works through the turnover a requirement actually implies, in the currency the reader is depositing, so two offers can be compared rather than admired.
The same approach runs through the bankroll pieces: staking that survives a losing run, why chasing a requirement is usually the expensive option, and when walking away from a bonus is the correct answer.
