Before you connect any bot

  1. Type the official address yourself (github.com). Don’t follow links from DMs, WhatsApp or Telegram groups. You can check a website for look-alike domains.
  2. If it uses exchange API keys, turn off withdrawal permission and restrict the key to the bot’s IP addresses if your exchange allows it.
  3. Start with an amount you can afford to lose and check the fees above against your trade size.
  4. Be suspicious of guaranteed or daily returns. They recur throughout the cases on our watchlist.
