What wagering requirement is fair for a crypto casino bonus?

At a 3% average house edge (typical for slots), the breakeven wagering requirement is 33x. At 2% house edge (high-RTP slots only), it is 50x. Any wagering requirement above the breakeven point means the bonus has negative expected value, and you lose more clearing it than it is worth. Most major crypto casinos set wagering at 40x or higher, which puts them in negative EV territory for the average player.
