As a completely free-to-participate platform, the Borrow Feature offers a unique opportunity for users to leverage their BTC, ETH, ABR or USDT holdings as collateral to obtain Bitcoin tokens World ($BTCw).
You can borrow $BTCw by collateralizing your **BTC, ETH...** at 0% interest. You can receive your **BTC, ETH...** back whenever you want securely.
### **1. Using BTC, ETH... or USDT as Collateral:**
The borrowing system allows users to use their **BTC, ETH...** holdings as collateral. This means that users can temporarily lock in a portion of their **BTC, ETH...** assets to access BTCw tokens.
