You say you do not want to put your capital at risk, but the methods you are employing now carry very significant risk. Remember, there is no such thing as risk free easy quick money. To reduce it you could focus on stable incremental gains, you could consider the following lower-risk strategies:

1. Stablecoin Lending on DeFi Platforms: Platforms like Aave and Compound allow you to lend your stablecoins and earn interest. These platforms are generally considered safer because they involve lending assets that are less volatile.

2. Stablecoin/Staking Pools: Instead of holding stablecoins alone, consider providing liquidity to stablecoin/stablecoin pools on platforms like Curve Finance. These pools typically offer lower risk compared to other cryptocurrency pools because they deal with stable assets.

3. High-Interest Savings Accounts: Some crypto exchanges offer high-interest savings accounts for stablecoins. These accounts provide a safer way to earn interest on your holdings without engaging in more complex DeFi activities.

4. Dollar-Cost Averaging: Regularly invest a fixed amount into a diversified portfolio of assets. This strategy reduces the impact of volatility and avoids the risk of making large investments at unfavorable times.

5. Consider diversifying part of your portfolio into assets outside of crypto, particularly bonds.
