Simple Crypto Price Alerts

• People send /start and tap New alert
• They pick a coin — Bitcoin, Ethereum, Solana, or type another tracked coin — and see its current price
• They choose what to watch — rises by %, falls by %, or reaches a price — and send the number
• The bot checks prices every minute and messages them once when the alert hits, then removes that alert
• My alerts lists what they are watching and lets them remove one coin or everything

• Connect your Telegram bot: Settings → Bots → paste the token from @BotFather.
• Press Deploy. The bot only answers once the flows are published.
• Wait about a minute so the Prices updater loads the first prices, then send /start and add a test alert.
• Optional: change trackedCoins (CoinGecko ids, comma-separated) and maxAlerts under Variables.

Good to know

• Prices come from CoinGecko's free public API, loaded once a minute for the whole bot — no API key, and no request per user.
• People can only set alerts on coins in the trackedCoins list. It ships with Bitcoin, Ethereum, Solana, and TON; add any CoinGecko coin id.
• Each person can keep a limited number of alerts at once (5 by default, set in maxAlerts), so one user cannot pile up hundreds.
• An alert fires once and is removed, so nobody gets the same message every minute.
• Alerts are checked about once a minute, so a spike that reverses within that minute can be missed. It's a heads-up tool, not a trading signal.

Common questions

• Which coins should people be able to watch?
• How many alerts can one person keep at once?
• Do you need more than alerts — charts, scans, a digest, or paid tiers? Then the Advanced Crypto Terminal fits better.

Keep in mind

• Don't promise instant alerts — prices refresh once a minute.
• Don't present alerts as financial advice or trading signals.
• Don't put hundreds of coins in trackedCoins — one CoinGecko call covers the whole list, and the free API has rate limits.
