Frequently Asked Questions
What is a Binance API key and why do I need one?
A Binance API key is a secure credential that allows CoinTech2u to interact with your Binance account. It enables the AI trading bot to place and manage trades on your behalf without giving it access to withdraw funds. You need an API key to connect CoinTech2u to your Binance account for automated trading.
Why do I need to restrict my API key to specific IP addresses?
Restricting your API key to CoinTech2u's 30 trusted IP addresses is a critical security measure. It ensures only CoinTech2u's servers can use your API key to execute trades. Even if someone obtained your credentials, they could not use them from an unauthorized IP address.
Is it safe to share my API key with CoinTech2u?
Yes, it is safe. The API key only has trading permissions -- it cannot withdraw or transfer your funds. Combined with IP restrictions and 2FA protection, your Binance account remains fully secure. Your funds always stay in your own Binance wallet.
What is Hedge Mode and why should I enable it?
Hedge Mode allows you to hold both long and short positions simultaneously on the same trading pair. CoinTech2u's AI bot uses this to manage risk more effectively by hedging positions in volatile markets. Without Hedge Mode, the bot cannot execute its full range of trading strategies.
