CoinPoker
Your sample is +20% ROI across 100 entries, with +$200 on $1,000 invested. To finish at +10% after 100 more entries, those entries need $1,000 in total returns. CoinPoker's listed 15% rakeback belongs on a separate line only after it is credited; it is not tournament winnings or an overlay.
Listed restrictions: US, UK, AU. Check eligibility and local law before signing up.
