Bankroll 📈 Live odds & line movement
Line movement: we remember the last odds you saw on this device and show ▲/▼ when a price changes. Lines move from news, injuries, and where money flows — movement is information, not a guarantee.
🚀 Market movers (crypto, 24h)
Data: Binance.US / CoinGecko public APIs, delayed. Big daily moves cut both ways — yesterday's top gainer is often today's loser.

🎯 Bet types: pros & cons
Moneyline
- Simplest: just pick the winner
- Favorites pay little; one upset erases many wins
Point spread
- Evens out mismatched teams near 50/50
- Standard -110 means you need ~52.4% just to break even
Totals (over/under)
- No need to pick a winner
- Weather, pace, garbage time — high variance
Parlays / SGPs
- Small stake, big payout
- Vig compounds each leg; books' highest-margin product. Same-game legs are correlated and priced to favor the house
Player props
- Fun, follow specific players
- Lower limits & often higher hold; injury/minutes risk
Live / in-game
- React to what you see
- Fast taps + emotion = chasing losses; delayed feeds
"Boosts" & promos
- Can be real extra value
- Wagering requirements; designed to build habits
Futures
- Season-long interest from one bet
- Money locked for months, often 20–40% hold
💼 Investments: pros & cons
Individual stocks
- Own part of a real business; long-term growth & dividends
- One company can drop 50%+; hard to beat the index
Index ETFs
- Instant diversification, low fees, historically strong long-run returns
- Still falls in crashes; boring (that's the point)
Crypto
- 24/7 market, potential for big gains
- Extreme volatility, hacks/scams, no earnings to anchor price
Options
- Leverage; can hedge positions
- Most short-dated options expire worthless; time decay works against buyers; selling uncovered can lose more than you put in
Margin
- More buying power
- Borrowed money amplifies losses; margin calls force selling at the bottom
High-yield savings / T-bills
- Safe-ish, predictable yield
- Won't grow much beyond inflation
Investing ≠ gambling: stocks have positive expected value over time on average; sportsbooks have a built-in edge against you. Neither is guaranteed.
🏦 Bankroll tips
- Only use money you can afford to lose completely — never rent, bills, or borrowed money.
- Set a fixed monthly entertainment budget; stake 1–2% of it per bet.
- Use the apps' deposit limits, time limits, and cool-off tools.
- Never chase losses. Walk away after a set loss or time limit.
- Track every bet. Most people overestimate their win rate.
- Build an emergency fund and retirement savings before speculating.
- Shop lines across books — a half-point or 10 cents matters long-term.

The win chance baked into odds. -150 → 60%. +200 → 33.3%.
The book's cut. Two sides at -110 add to 104.8% — that extra 4.8% is the house edge.
Average result per bet if repeated forever. Most bets are negative EV.
Final odds before start; beating it consistently is the best skill signal.
Yearly fund fee. 0.03% vs 1% compounds to a huge difference.
Spreading money so no single loss sinks you.
