Every cashout target has the same base −1% EV (−0.97% after rakeback). Stake's crash curve is designed so multiplier × P(win) = 0.99 for all targets. Lower targets mean less variance, not better odds.

Crash Predictor Tools are SCAMS

Stake Crash is provably fair through a pre-committed hash chain: every round is one link of a 10-million-hash chain, salted with a Bitcoin block chosen after the chain was published, so all results were fixed before anyone ever bet. (Unlike Dice or Mines, Crash does not use your client/server seed pair, and stake.com and stake.us each run their own chain.) No tool can predict future results. Any "crash predictor" is either a scam or gambler's fallacy dressed up in a UI.

Each round is independent. Past crashes have zero effect on future results.
