Learn exactly what you are reading
34 bilingual explainers about markets, odds, evidence and control. Every concept has one stable topic ID used by Betty.
Asian Total Over 1: what happens with exactly one goal?
This is a whole Asian line: with exactly one goal, the stake is returned; it is not a win.
Open explainer →Asian Total Over 1.25: why can the result be a half-settlement?
A .25 line splits the stake in two: half on Over 1 and half on Over 1.5.
Open explainer →Over 1.5: the line without a refund
Two or more goals are needed in the stated period to win; with 0 or 1 goal, the wager loses.
Open explainer →1H vs FT: same line, different period
`1H` means first half; `FT`/match means the period defined by the operator, usually regular time.
Open explainer →BTTS / Both Teams To Score
BTTS Yes wins only when each team scores at least once in the market period.
Open explainer →Decimal odds and implied probability
An odd can be converted into an approximate market probability: 1 divided by the odds.
Open explainer →Bookmaker margin (overround)
Odds usually include a margin: the implied probabilities of all options add to more than 100%.
Open explainer →Expected value: estimated probability versus price
A discussion of value starts only when you have an estimated probability, an available odd and a way to verify it over time.
Open explainer →xG: chances created, not goals promised
Expected Goals (xG) is a statistical estimate of chance quality, not a counter of goals that are due to arrive.
Open explainer →Live snapshot: why minute and timestamp matter
A live decision can be evaluated only with information available at that time: score, minute, odds, market and the live data used.
Open explainer →Win rate, refunds and ROI are not the same thing
Win rate counts winning decisive results; ROI measures net profit against total stake. Refunds need separate reporting.
Open explainer →CLV: comparing taken odds with closing odds
Closing Line Value compares the price obtained with the market price at closing; it is an indicator, not a final verdict on profit.
Open explainer →Single versus accumulator: what changes?
A single has one outcome; an accumulator needs every leg to settle favorably for a full win.
Open explainer →Correlated exposure: more tickets, the same story
Two or more wagers can depend on the same goal, match or assumption; their risk then moves together.
Open explainer →Bankroll and units: measurement language, not a staking order
A unit is a fixed reference for a ledger; it is not an invitation to increase stake after a result.
Open explainer →Variance and drawdown: why streaks are normal
Short-term results can swing widely even when a method has a reasonable estimate; drawdown is the decline from a previous peak.
Open explainer →The full ledger: the only base for verifiable ROI
For each entry, save before the result: timestamp, market, selection, odds, stake/units, context and then settlement.
Open explainer →Posted result versus prospectively recorded wager
A result posted after the match shows what was reported; a prospective wager shows that selection, odds and time were fixed before the result.
Open explainer →Why chasing losses is not risk control
Increasing exposure after a loss changes financial risk; it does not change past probability or rewrite the previous result.
Open explainer →What data is missing before saying “this is how they choose matches”
A repeated market is not the same as the rule that selects a match. A selector needs rejected candidates too, not only published ones.
Open explainer →Prematch versus live: same teams, different information
Prematch uses information before kick-off; live also includes events already produced, and odds can move quickly.
Open explainer →Void and push: when the stake returns
A push/void normally means the eligible stake is returned; it is not a win and it does not repair other selections.
Open explainer →Asian Handicap 0 / Draw No Bet
With Asian Handicap 0, the chosen team needs to win; on a draw, the stake is normally returned.
Open explainer →Double chance: two outcomes from 1X2
Double chance combines two of the three regular-time match outcomes: 1X, X2 or 12.
Open explainer →Break-even threshold: what percentage an odd requires
For decimal odds, the raw break-even threshold is 1 divided by the odds before adjusting for margin and other costs.
Open explainer →N and period: without them, a percentage is incomplete
`N` states how many observations enter a metric; the period states when they were observed. Both are needed for context.
Open explainer →Settled selection: why the definition matters
A settled selection is one delivered and then settled under the market rule; it can enter a metric when definition and period are clear.
Open explainer →Betty Score: filtering and routing, not win probability
Betty Score is an internal indicator that helps filter and route cards into categories; it is not an event's chance percentage.
Open explainer →Flat stake: a comparison method, not a staking instruction
Flat stake uses the same hypothetical unit for every selection when measuring a series, so results can be compared without stake changes.
Open explainer →Regular time: which interval is settled?
Many football markets refer to regular time; extra time and penalty shoot-outs can be excluded under the operator rules.
Open explainer →Privacy by default: less data, clear purpose
A privacy-first experience asks for only necessary data, explains the purpose and offers a clear route for contact and control.
Open explainer →Official account, not messages impersonating Betty
Use only the official account and links shown on the website. Do not send passwords, private keys or authentication codes in chat.
Open explainer →Direct crypto: less data requested by Betty
The direct crypto route avoids a Betty checkout profile: you control your wallet and verify the transfer without sending secrets in chat.
Open explainer →Tribute checkout: payment data stays with Tribute
If you choose Tribute, checkout is a Tribute experience in Telegram; Tribute's rules and privacy policy apply to that part.
Open explainer →No topic matches this search.
