Jetbi: up-or-down bets in Telegram

Jetbi is a Telegram mini app on the TON blockchain where a participant guesses whether a price will go up or down. A round lasts 15 seconds. These are bets on short-term price movement, not investments. 📈

This page is for reference and is written for adults. It does not urge anyone to bet and promises no income. If you are under 18, or betting is banned in your country, the app is not for you.

Up or down in a quarter of a minute

The mechanic fits in one sentence: you pick a direction, wait for the round to end, and get a result. The format is close to binary options, which many countries restrict or ban.

A very short round changes behavior. Decisions are made in seconds, emotion pushes out calculation, and the number of bets in an evening climbs fast.

What "on TON" means

Payments run in TON cryptocurrency, so you need a wallet connected to the app. The blockchain records transfers, but it does not guarantee that the game itself is fair.

• Exchange rate. A TON balance moves regardless of the round outcome, so the result in money can differ from what you expect.
• Network fees. Each transfer costs a small amount, and with frequent bets those add up.
• Irreversibility. A mistaken blockchain transfer is almost impossible to get back.

How a bet differs from a forecast

Over 15 seconds a price moves almost at random. Charts, indicators and gut feeling add little on such a stretch, and any pattern drowns in noise.

If the payout for a correct bet sits below the stake by a margin, the operator comes out ahead over time even when half of the guesses are right. Check payouts and fees in the app's rules.

What you cannot see from outside

A player cannot check where prices come from or how a round result is set. Look for a description of the quote source and a way to contest a result.

The project's channel is small and the project is young. Do not keep an amount in it whose loss would upset you.

Rules of caution

1. Set a monthly limit whose loss will not hurt your budget.
2. Do not bet borrowed money or money meant for bills.
3. Do not try to win it back by doubling the stake: losses then grow faster.
4. Do not enter a seed phrase or connect a wallet to unfamiliar sites.
5. Compare the bot and support names with the ones in the profile and the project channel.

Law and addiction

Bets on price changes are treated as gambling or as unlicensed trading in many countries. Some allow them only with a licence, others ban them. Following local law is the user's responsibility. 🔞

If you spend more than planned, hide spending or borrow money, stop and ask for help. Most countries have free helplines for people with gambling problems.
