Holding Bitcoin and optimistic about the market but don't want to sell? In this case, you might consider a strategy: use BTC to exchange for liquidity while maintaining your crypto exposure.

Specific steps:

**Step 1: Collateralize for Interest**
Deposit BTCB into a leading lending protocol, collateralize it, and borrow stablecoins. The annualized yield is about 1.11%. This way, you haven't sold your BTC but can still borrow stablecoins.

**Step 2: Beware of Liquidation Threshold**
A key point—these protocols typically set the liquidation price at 70% of the collateral value. If your LTV( borrowing ratio) is too high, a decline in the coin price could easily trigger liquidation, so make sure to leave enough buffer.

**Step 3: Stablecoin Appreciation**
Transfer the borrowed stablecoins to a top-tier exchange for wealth management, leveraging its 20% flexible lending yield. Note that this high yield is limited to the first 50,000 units; beyond that, the returns will drop significantly.

**Yield Calculation**
Suppose you borrow at 50% LTV: the wealth management yield is 20.06% minus the borrowing cost of 1.11%, resulting in a net yield of approximately 18.95%. Multiplying by the 50% borrowing ratio, the final annualized return can reach 9.48%.

The core of this strategy is to generate additional income from idle assets while maintaining BTC exposure. But be sure to carefully assess the risks.
