Building a cryptocurrency portfolio that maintains a certain stability in both ups and downs requires good diversification and a balance between different types of digital assets. The strategy for creating such a portfolio usually includes:

### 1. **Large Caps (30-40%)**

- **Bitcoin (BTC)** - 20%: Considered a "store of value", commonly used as a hedge asset against altcoin market volatility.

- **Ethereum (ETH)** - 15%: Leading smart contracts platform, widely used in DeFi, NFTs, and the metaverse.

### 2. **Stablecoins (10-20%)**

- **USDC (USD Coin)** - 10%: Trusted and audited stablecoin, ideal for protecting capital and maintaining liquidity.

- **DAI** - 5%: Decentralized stablecoin, known for its security in the decentralized finance (DeFi) sector.

### 3. **Alternative Smart Contract Platforms (20-30%)**

- **Binance Coin (BNB)** - 10%: Used for transactions on the Binance Smart Chain, an alternative to Ethereum.

- **Polygon (MATIC)** - 5%: Focused on Ethereum scalability, attracting major partnerships and growth in usage.

- **Solana (SOL)** - 5%: High-speed platform that competes with Ethereum for smart contracts and NFTs.

### 4. **DeFi and Metaverse (10-15%)**

- **Aave (AAVE)** - 5%: One of the leading lending and borrowing platforms in the DeFi sector.

- **The Sandbox (SAND)** or **Decentraland (MANA)** - 5%: Both operate in the metaverse and gaming sector, with great growth potential.

### 5. **Ethereum Interoperability and Competitors (5-10%)**

- **Polkadot (DOT)** - 5%: Interoperability platform that facilitates communication between blockchains, an important trend in the market.

- **Cardano (ADA)** - 5%: Focused on scalability and sustainability, with a strong community and continuous development.

This portfolio provides diversified exposure across core assets (BTC, ETH), stablecoins for liquidity, alternative smart contract platforms, decentralized finance tokens, metaverse, and interoperability. Keep in mind that regular rebalancing is important to keep up with market changes and manage risk.
