According to Blockworks, the cryptocurrency market has undergone significant changes over the years, with many coins that were once popular now replaced by newer trends. Five years ago, investors might have filled their portfolios with coins like Litecoin, XRP, Stellar, and Cardano. However, the market has shifted, and what was once considered valuable has changed. Today, AI agent memecoins and other emerging trends have taken the spotlight, leaving some investors feeling out of touch.Despite these changes, some aspects of the market remain constant. The top three cryptocurrencies, Bitcoin (BTC), Ethereum (ETH), and XRP, continue to hold their positions as they did years ago. However, outside of these leading coins, the market landscape has transformed significantly. Many coins that were once in the top 25, such as NEO, IOTA, Tezos, Ontology, NEM, and Zcash, have fallen in rankings, with only Tezos barely remaining in the top 100. They have been replaced by newer projects like Solana, Toncoin, Avalanche, and Chainlink.As the market anticipates another altcoin season, some older coins, referred to as "dino coins," are striving to stay relevant. An analysis of price data for coins in the current top 250 by market cap reveals that one-third of these coins have seen their Bitcoin ratios rise over the past year, indicating they have outperformed Bitcoin. Among these, about 20 are dino coins, which are tied to projects launched at least five years ago.However, newer coins continue to dominate the market, with some experiencing exponential growth in their Bitcoin ratios. Memecoins like WIF and other tokens such as Mantra, Virtuals, and Aerodrome have seen significant gains. Interestingly, the market is also paying attention to some lesser-known dino coins. While well-known coins like DOGE, XRP, XLM, BNB, and TRX have rallied recently. This altcoin season appears to cater to a diverse range of investors, including those who are not concerned with following mainstream trends.
