In the cryptocurrency market, investors seeking stable returns often choose to focus on mainstream coins with high liquidity and mature technology. Taking Bitcoin (BTC) as an example, its fixed total supply, decentralized characteristics, and market positioning as 'digital gold' make it a long-term value storage tool against inflation. Ethereum (ETH) has built a vast decentralized application ecosystem through smart contract technology, and after the 2024 upgrade, its transaction speed has increased to hundreds per second, with transaction fees as low as a few cents, becoming the infrastructure for blockchain innovation. Binance Coin (BNB) relies on the ecosystem of the world's largest exchange, with application scenarios covering over 200 real-world fields, and has seen a growth of 8000 times over eight years, demonstrating the robust appreciation potential of platform tokens.

Implementing this strategy requires combining three core methods: first, adopting a dollar-cost averaging strategy to regularly and consistently purchase mainstream coins, smoothing out market volatility risks over time; second, constructing a portfolio by proportionally allocating funds to BTC (40%), ETH (30%), BNB (20%), and SOL (10%), which are both liquid and have ecological value; finally, strictly setting a stop-loss line, triggering an automatic liquidation mechanism when the decline of a single coin exceeds 15%. Historical data shows that between 2019 and 2024, the dollar-cost averaging portfolio focused on mainstream coins achieved an annualized return of 28.5%, significantly higher than the 19.2% of diversified investment strategies.

The advantage of this strategy lies in the fact that mainstream coins account for over 70% of market liquidity, supported by continuous inflows of institutional funds. By 2024, the Bitcoin ETF held by asset management giants like BlackRock has surpassed $50 billion. At the same time, regulatory agencies are accelerating the compliance process for mainstream coins; the U.S. SEC has classified BTC, ETH, and others as non-securities, significantly reducing policy risks. Investors should note that although emerging public chains like Solana (SOL) have processing speeds of up to 65,000 transactions per second, their technical stability still needs time to be validated, and it is recommended that the allocation ratio does not exceed 15% of total assets.
