Base RTP: 96.0%

Strategy: Monitor dynamic price, buy saat under 110x

Teknik: Track personal session RTP
Threshold: Jika session RTP < 90%, consider buy feature
Logic: Reset variance dengan instant feature

Scenario: 1 hour, 100 participants, prize pool $10,000

Formula: f* = (bp - q) / b
Dimana:
b = odds yang didapat (contoh: 95 untuk 100x buy)
p = probability win (RTP bonus / 100)
q = probability loss (1 - p)

Contoh: Buy 100x, RTP bonus 96.5%
f* = (95 × 0.965 - 0.035) / 95 = 0.0189
Recommendation: 1.89% dari bankroll per buy
