Lately, I've been thinking about how to choose reliable cryptocurrencies. There are so many coins on the market, each claiming to have potential, but only a few are truly worth holding long-term.

Over the years of navigating the crypto space, I've discovered a pattern. During bull markets, everyone chases after altcoins, hoping to get rich overnight, but when a bear market hits, these coins often suffer the worst declines. Conversely, the mainstream coins with higher market caps, while not experiencing as dramatic gains, tend to be much more resilient. So, when selecting cryptocurrencies, first look at the overall market trend, then consider the project's reputation, trading volume, and liquidity.

Regarding the top-ranked cryptocurrencies by market cap, the landscape has changed quite a bit over the years. Bitcoin has consistently held the top spot, with a current market cap of about $1.55 trillion, accounting for roughly 57% of the entire crypto market. Ethereum ranks second, with a market cap of around $255 billion and a market share of 9.4%. Behind them are Ripple, Tether, Binance Coin, Solana, and others. However, these rankings are not set in stone; coins like Filecoin and Luna, once in the Top 10, have long been pushed out. These coins attracted many investors during market hype, but their high volatility and risks led many to lose money in the end.

My personal recommended cryptocurrencies are mainly Bitcoin, Ethereum, Ripple, and Solana. Bitcoin, as the king of crypto, has a fixed supply of 21 million coins, halving every four years, creating a deflationary mechanism that makes it especially valuable. Recently, with the launch of spot ETFs, institutional funds have poured in, pushing the price upward. Ethereum, while not as large in market cap as Bitcoin, supports smart contracts and has the richest ecosystem, with a total value locked (TVL) of $93.1 billion, ranking first among all public chains.

Ripple is backed by Ripple Labs and maintains close relationships with global financial institutions and government agencies. Its transaction speed is astonishing—handling between 1,500 and 3,400 transactions per second, far surpassing Bitcoin and Ethereum. Solana claims to be the "Ethereum killer," with extremely low transaction fees—about $0.00025 per transaction—and a throughput of up to 65,000 transactions per second, with real-world performance around 3,000 to 4,000 TPS, offering excellent cost-performance.

Another coin worth noting is TAO, which combines artificial intelligence and blockchain. Its underlying network, Bittensor, aims to build a peer-to-peer machine learning service marketplace. Chainlink connects blockchain with real-world data and is a genuinely practical project, unlike those "air coins." Dogecoin, although started as a joke, has maintained popularity thanks to Elon Musk's support.

As for stablecoins USDT and USDC, they are pegged 1:1 to the US dollar, with volatility not exceeding 1%. They are mainly used for holding cash and are unlikely to generate significant returns.

Regarding investment strategies, my experience suggests that long-term investing is generally more suitable for most people than short-term trading. Short-term trading sounds lucrative, but in reality, it's very difficult to predict market movements accurately every time. I learned this the hard way—back in 2018, I bought Bitcoin around $5,000, and when it rose to $7,000, I rushed to sell. Later, it surged to $12,000, and I was kicking myself for not holding on. Those who can stick to long-term holding often see the best returns in the end.

Newcomers often make the mistake of being lured by the low prices of altcoins, thinking that if they reach a penny or a fraction of a cent, their holdings in billions could make them rich. But the harsh reality is that most altcoins eventually go to zero. Some also swap their holdings of high-market-cap mainstream coins for a bunch of junk coins, only to end up empty-handed on both ends.

If you're a conservative investor, I recommend sticking to Bitcoin and Ethereum—the most well-known cryptocurrencies. If you have some trading experience, you can consider allocating a portion to Solana, Dogecoin, or Cardano. Avoid highly volatile meme coins; their risks are too high and unsuitable for long-term holding.

Finally, I want to emphasize that regardless of which cryptocurrencies you choose to invest in, you must clarify your goals, know when to cut losses, and avoid blindly following the herd. For long-term holding, diversify your assets across different platforms, and even consider transferring some to cold wallets—physically isolated storage—to prevent yourself from selling impulsively due to price fluctuations. Investing in cryptocurrencies is like a marathon; persistence is the key to being the ultimate winner.
